Actually, rather than bill you for the time you have already played, they bill you for the time you will play. So that is why you must have it paid before the end of september, because at that point you'll be paying for october playtime which is, theoretically, the last playable month before version shift/beta test/temporary break in P2P.

Legacy status triggers about as soon as it procs that you have 90 days paid, and since we currently only have 30-day billing periods, as soon as your third billing period hits, you'll recieve it.
