I'm just a n00b here, but have been shootin' rifles for a long time. . .

Seems to me there is much over-thinking taking place here.

The guys said rapid fire, so it would seem pretty simply that muzzle rise/flip/whatever you like to call it is being lessened in the very brief time allowed between shots.

As for barrel length, there is a reason sniper rifles have long barrels. And even at the much lower muzzle velocity of the .22lr, the round has left the rifle behind long before the barrel rises.

And regarding harmonics or vibrations, it is my understanding that these phenomena are more meaningful when measured between controlled shots; a locked down bench rest for sighting or checking accuracy from a bench rest when testing a particular round for example; one has to chalk up an unknown percentage of variance to these effects, the rest being the rifle/shooter/ammo.

So, again, in the OP's scenario, I would have to say it is purely muzzle rise/flip. The gun is obviously moving around so much during rapid fire bursts that I don't see why would you even care about vibration/harmonics?
