Turn around dash and jumps

How do you perform turn around dashs towards your opponent or back turned jumps like
With LAU: PPPK (or d+k don't remember) then croush dash towards your opponent (with your back turned) then jump above opp's rising attack.
or with Lion FC f+P+G, b,f+K+G, then jump above opp's rising attack
I saw that in some clips for a while now but still don't manage to do it properly.Please Help!! ^_¨

 

Sorry I've made a msitake I'm wasn't asking about turn around dash, but rather about back turned dash or jump TOWARDS your opponent,someone has any clue ?

 

Why doesn't it work ? does Lau turn around when you try to dash ?

 

Why doesn't it work ? Does Lau turn around when you try to cd or jump ?

 

Yep I don't manage to jump above rising attacks without turning around, especialy after Lion b,f +K+G.
