Hey Dean!!!! What up????
Dude, Im afraid you're wrong!
Indy airs are grabbed frontside. Perhaps the differece with a fs. air would be that you grab behind your back leg. It can be a fs. or bs indy as long as your grab's legit. But NEVER a backside grab. You're right about one thing though, Sete's deffinetly doing a FS.Air. CHEERS MATE!
