I made a living for several years by gunsmithing, most of which was building and fitting stocks, installing optics, installing and regulating sights. At the same time, my business offered private and class instruction on handguns and rifles.
It's 100% bunk to say a rifle will produce a different POI based on the shooter. BUT, it's 100% fact different shoots will often not properly or IMPROPERLY sight in the same way, whether be it through a scope or iron sights. How many shooters have picked up another fellows rifle and immediately noticed the reticle in their scope was cock-eyed? The shooter likely never noticed - because it's level the way he holds it! Or how many times have you picked up a fellow shooters' rifle then struggled to fit an appropriate eye relief or appropriate cheek weld? That's a safe bet you won't be positioned relative to the sights or scope in the exact same way the original shooter. If you DO find that same spot, you'll shoot exactly the same as the owner, if you don't, you won't.
Recoil for hold is a different game, most shooters don't actually shoot well enough, especially offhand where it would matter most, such they'd notice a little extra movement. The differential in their movement during their trigger stroke USUALLY will make far more difference when on the bench, and a lack of offhand accuracy typically won't expose the dwell time recoil effect either.
