Lauh sau vs. Huen sau

Hi All,
I've been getting emails asking why the huen sau like motion in TWC forms leaves the centerline. We are taught that the 'huen' sau SHOULD stay in the center but that the 'lauh'(flowing) sau leaves the center to flow around an opponent's arm in order to get to the outside from the inside. If a person's arm is on top of mine he has a superior position since the arms hang down naturally and he has gravity on his side. The object of the lauh sau is to keep the circle as small as possible while sticking to the arm like a snake crawling up bamboo and getting your arm on top. It's sometimes exaggerated in the forms for demonstrative purposes. Our huen sau stays in the center as is the norm for most WC.
