I think the point is more you have to go all the way to manual trim to disable MCAS. For Lion Air, the pilots didnt run (or even recall) the checklist so didn't disable MCAS. However Ethiopian appears much worse, pilots did run the checklist, had some success with MCAS turned off but couldn't operate the manual trim (unclear why). They then made the fatal decision to turn back on electric trim (and MCAS with it) and MCAS almost immediately nosed them down into an unrecoverable state.
