Replying to flatspins in pipe

i just recently learned flatspins on the trampoline and i was wondering if its the same on skis rotation wise. i sorta put my body in a position of a rodeo and then bring my knees up to my chest.

i was curious if a flatspin in the pipe is different from the rotation off of a jump, because whenever i watch movies they look a bit different

also i notice that pretty much all the pros go alley oop when doing it in the pipe. is it easier to do alley oop then to do it regularily? thanks
