Moving like someone does not mean the movemnt is a exact copy of what one sees, learn a series of moves then teach them then look at what you have taught, there is change even at this point. Also if one learns the NATURE OF AN ART SUCH AS , Crane :Bird, Tiger :feline Dragon etc. Then ones moves will be different in each style, but only in essence , not in Physicality, a punch is a punch is a punch, in SD the Lohan or 1-30 are taught as a base. this is why the SD system looks as it does. THe Neuro pathways are ingrained and this bleeds over into the other methods < Tiger etc. so I think it is more of a Neuro training through repetition that causes the style to look as it does, not as some would think , that it is Karate not Kung Fu.
