a switch nollie is just a fakie ollie imho, if you skate in so called "real switch" the engine will always tell you crap about the trick you did, since it doesn't realize you are riding switch correctly. but on the other hand when you do a ride in real switch and you do a nollie (flicking top down) you are doing a switch ollie were it just says nollie, which is correct from the engines view... hope that makes any sense to you
