reverse ninja vanish

what is the difference between the normal ninja vanish swing and reverse ninja vanish swing? i mean in shinya kido tut, he’s just doing the same.

If you’re referring to the swing of your NTH to make the loop, the difference is that for reverse ninja vanish the loop catches the yo-yo around the side furthest from you rather than around the side closer to you. Your TH will pass under both the yo-yo and your NTH.
