This guy didn't go off script. It seems like he was the only one of the three who knew the script. The script says to stop if the trim adjustments stop when you counter with manual trim input. MCAS, by design, stops. You can see where MCAS stops trimming nose down on the preliminary Indonesian report (they graph both the fatal flight and the previous flight).
