not quite true. The rule was (and is until the new rule kicks in) that if you had not cleared into Z by check-in, you could not get on a wait list.
I have one 2 different occasions called 3 days before, 2 days before, 1 day before a NRT-ATL flight booked in M and not had the Z clear. Then, day of, 7 hours before the flight, I called in again and got it cleared.
Just want to avoid misinformation
