Good thought! In the SNT form of CSL Wing Chun there is something very similar. A "tight" version of the Huen Sau from the wrist and a "wider" version of the Huen Sau that comes from the elbow. Just guessing....but I would think that Robert Chu picked up the "tight" version from his studies of Ip Man and Yuen Kay Shan Wing Chun and the "wide" version from his studies of TWC. He saw value in both and so he does both.
TWC actually has both a tight and a wide one as well. In short it is important to see it simply as circling hand. If your opponent is unarmed you are "tight", not loosing contact. If armed however, especially with a knife, that will get you cut. I didn't actually know the history of Chu your briefly hit on there that involved TWC otherwise I would have gone straight there.
