Indeed - at least while doing a 60 degree bank you are in forward flight and you have the benefit of translational lift. Plus, you're more than a few feet off the ground !
Hover performance is marginal in an R22 at best when close to all up weight, let alone over it ! Even at sea level you could find yourself struggling to get a decent hover, then it'd be all too easy to overpitch it, or catch a skid and roll the whole thing over.
