AFAIK MCAS would apply up to 5ish degrees of AND trim if it sensed too high AOA. If the out of trim conditions were still there it would not apply trim again until one of several system reset triggers happened. One of those was the pilots using the trim thumb switches. If the pilots hadn’t used the trim after the first MCAS trim application MCAS would not have reactivated. Obviously, that doesn’t make MCAS okay, as we are all trained to fly with the aircraft in trim.
