No, if the gas is retained internally, it no longer possesses a jet effect to the external atmosphere which is how a brake works. A brake redirects gas backward or sideways radially to negate or counter-effect the forward jet of gas from the muzzle causing effect of recoil.

- moderator muzzle brake
I’d argue that the gases acting upon the port faces adjacent to the bore are what is counteracting the recoil, rather than the thrust of the gas.
The gasses in a moderator are pushing from the bolt face to muzzle. They are not geo aware. Any pressure on the port faces of the enclosed moderator is equally distributed to the bolt face.
As @The Bear says, it is the slowing down of the jet thrust out of the muzzle which reduces the recoil. The peripheral area of the cylindrical column of gas has proportionally more than the inner so a close fitting baffle stack and the longer it is the larger the dissipation of energy.

You can argue the physics all day
I have the data to support the hypothesis
Weight is not the defining factor in the impact of a moderator on recoil reduction
The correlation between weight and recoil reduction was not linear in the yes we ran on 23 mods

I thought it strange too, but I speak as I find.
Have you tried the same with an unmoderated rifle?
Me too!

I have a Lawrence Precision Nexus that came with a second hand rifle. I was told by Simon Lawrence that it had had 15,000 .308W and 30-06 rounds through it...I have added another 2,000 plus .308W since owning it.
Relatively light for its size.
Subjectively it seems to be as equally effective if not better than most at attenuation. Subjectively, as difficult to know what your own is like in relation to others. I asked fellow shooters how mine compared after we had been deafened by someone else's ineffective moderator and were comparing it with our perceptions of the others.

Was that with or without hearing protection??

Probably with hearing protection!
Muzzle brakes have the advantage of compactness & can be quite isthetic on some styles of rifle. They don't however help you make friends. LOL.
Moderators are not pretty, but they do help you protect your hearing.
One problem with muzzle breaks is that they raise dust & muck clouds when used over bare ground. The muck gets everywhere - in your rifle , on the scope lenses, in your eyes, up your nose --- everywhere! It also impedes vision after the shot. You can get a dust problem with a bare muzzle rifle too, but nowhere near as bad. With a moderated rifle you don't suffer that way.
I sometimes shoot at the new Inverarnie range near Inverness & this has been a problem there. Hopefully in time the firing points will get some grass on them. - Till then I'll be taking a groundsheet to peg out under the muzzle.

I have a moderator on my .25-06 and a brake on my win mag, purely because the win mag is already a 26" barrel and by the time you've added on 6" of moderator and another 250-300g in weight it starts to make the rifle pretty unwieldy and heavy to lug about for long periods. Especially when I'm up in Scotland.
I have a moderator for the win mag but its stayed in the safe in favour of the brake of late.
My .45-70 isnt threaded so I couldnt use a mod on that even if I wanted to.
If I was given a choice of what to use all the time personally I would go with a brake, because they are lighter and more compact and because they dont upset the balance of the rifle as much. And I think they look better. Nothing worse than having a lovely looking rifle with a massive tin can on the end.
I like the set up I have at the moment because it gives me a choice of modded or not on the day depending on where I'm going. If I'm shooting near pheasant pens then I take the '06 because its quiet but if I'm going somewhere open where I might be taking longer shots then its the .300.
The other reason I like the brake is it doesnt heat up on the range. Mods get wicked hot really quickly, especially with cartridge like win mag which is a big case and lots of powder. I use my stalking rifles in long range target competitions at my club and the brake is great because it doesnt give off a haze like the mod does after a few shots.
Before anyone says it theres lots of people shooting brakes at my club so no issues with it.

Do
My zeroing range is a bog right now!
Do they work under waterFind a range further west: no danger of there being any dust...

Clubs should encourage members to stand over those shooting with brakes and hit them around the head with a rolled up newspaper every time they fire a shot next to someone without a brake. This is fair because it's what they do to others. If it's a magnum the newspaper should be changed to a tightly rolled magazine.
All brakes should be clustered together on firing details preferably the last one if there's time for it. Failing that unscrew them (added benefit of maybe losing them)
Brake shooters who don't check everyone has their muffs before letting rip should have the brake inserted somewhere forcefully. Brakes should not be allowed under cover no matter what - think of the poor RCO.
Scores for brakes should be reduced by at least 10%.

Oh yes there is.
Being pounded by the buffet from the wazzock next door's muzzle brake blast is much worse, for one.
