In some old videos,he seems to be trying to do some BSL forms and some movies he does the BSL “triple kick” (fronal with a jump,horse heel kick,tornado kick),but,i am not really sure if this kick is exclusive to BSL.
He learned a little, didn’t really understand it, and later criticized it, thinking it was only good for showing fancy looking moves.
-N- is correct.
Regarding that type of 3-kick combination, it’s commonly seen in the forms of many traditional Chang Quan (Long Fist) styles, of which BSL is only one.
