Not so much really. Look at the way things are thrown. A misty is a rodeo, just thrown forwards instead of back. Bio's are forward corks,  but a misty is not  a type of cork, its a spin with a complete inversion. The way I see it, tricks have backwards and forwards counterparts:
Back                                  Forwards
Rodeo                                Misty
Cork                                   Bio
D-spin                               The trick in question (Orbital?)
Another question is what the heck would a forwards thrown flatspin look like, but thats worthy of another thread.
And dont make me pull out my shit about underflips and overflips; Trust me, they have nothing to do with this at all.
