First instinct is that guy had no business flying a helicopter.
No part of that short approach and landing attempt was smooth. I'm certainly no expert (I do have a few right-seat hours in a R-22 tho

), but it sounds like one of the video commenters was on the right track: He may have been trying to land on a mobile heli-pad and got on it slightly cock-eyed, possibly teetering one skid off the side. Then, it looks like he pulls pitch to gain altitude and try again, but catches a skid and flips over.
Can't say for sure, but he could have been over his head experience-wise.
