Replying to Trick Definition

I saw an article a while ago that defined a switch misty 9 as approaching the jump switch, throwing a 180 and then doing a misty 7.

I was looking through the CFSA's guide to Big Air competitions that ranks tricks by DD (degree of difficulty) and noticed a switch rodeo 7, but no switch misty 7.

Can you do a switch misty or do you have to turn 180 and start in the air? I would think that it would be easier to start off the jump as your momentum naturally has you rotating 'forward' when you go off switch, much like how it is easier to back flip than front flip.
