Im really confused when I first saw the upside thing. They don't really fly, they just jump far.
In order to get im that position. Naruto have to turn 180 degrees horizontaly and 180 deggrees verticaly. If Naruto is in a hurry, I don't know why you have to go for troubling thing like. If Naruto need to jump again, he need to turn vertically and horizontaly.

PS: Maybe I'm just analyzing this upside thing to much.
