I saw the short video on the link you provided, but it's not clear
how it works since there are no pictures. My guess is that they
attach a bridle to the trailing edge such that when the rear lines
become short enough (relative to the front lines) the bridle pulls
in the trailing edge. Never heard of WindWing brand either.
