i unsderstand your question, and asked it mnyself once, but if you think about it the names are accurate. you do a swtich backflip, and youre just doing a backflip, but going switch.
but if youre doing a switch misty, as soon as you complete even 180 degrees of rotation, from there on out its just like a regular misty...
if we called what we currently call switch rodeos switch misties...a switch rodeo would look like a forward misty
im not sure i explained that well but yeah..
