It's simple, really. Recruiters like myself and college coaches see team jumping as a sign that a girl cannot or will not compete for her position or playing time. It is a sign of a girl moving around in order to get more of both far more often than it is a sign of a girl looking for a good fit. It is also a sign of nutso parents quite often, as well.
I can't help what you choose to see, but that is simplistic, not simple, because you string together a series of assumptions.
