Actually that's probably what happened to the Lion Air accident flight, not to the Ethiopian flight. There was not much trimming done on the Ethiopian flight, but on the Lion Air accident flight they did a lot of trimming while fighting MCAS. And the control column forces recorded by the DFDR seem to indicate that the Lion Air captain handed over control to the FO shortly before they lost control.
