EXUP Worldwide was born from the ashes of the original EXUP Brotherhood – the definitive forum for all those who have interest in Yamaha FZ, FZR, and YZF motorcycles.
Jason,
I think the guy got so caught up in lean angle that he forgot all about the contact patch. Maybe he thought the knee puck could substitute as the bikes' contact patch. You can push off a low-side with your knee puck but you still need ground clearance of your bikes' parts and some contact patch to do it.
If the guy wants to practice extreme lean angles he better work on providing more ground clearance for those exhaust cans. He's got them sticking out like hardcase luggage and hanging halfway down to the ground. Like you said, at least he was dressed for it.
Go for the ride but dress for the crash.
