So you are saying, that by rule, that no girl who plays ECNL in FL in the fall is allowed to play HS soccer? Are there any ECNL teams in FL? I did not think so, I guess this might be why. Do any FL players cross State line to play ECNL somewhere else and does that keep them out of FL HS ball?
Need more context to the rule you have posted, because a simple reading would also mean that a players could never, spring or fall, play for any team affiliated with a school or school coach? The wording as you have it posted is also talking about Basketball, and Baseball which have very strong off season programs in FL as well.
