My guess as to why girls are going from yj to tg but not so much in the other direction
1) More girls overall play yj so they have more to lose so to speak
2) Top level of yj is more competitive to make then top level teams of TG so many parents would rather have their kids play so called "A" team for top guns then play "B" level for yj
3)TG are doing a better and more aggressive job of recriuting kids from other clubs
