Based upon how quickly he whipped it out sideways, I'm guessing he wasn't going very fast and didn't go very far. Its just a little quick pop whip, and he is probably trying to go slow enough to try to catch some of the tranny directly on the back of the jump. Looks cool though.
Nah he's too far out to catch the tranny on the back of the jump, plus not a lot of jumps have those, most and just vert walls it's really only biggest jumps at super popular places like Whis and Mammoth that have trannies on the back of the lip. If you look at the side edge of the jump you can very clearly see it doesn't have one...
