And even if they had "disengaged the autothrottle", what would that have achieved? Nothing unless you then pull off a fistful of thrust...
Then you pull out the two page AD memo from Boeing and recall what it said: at the bottom of page two "Electric stabiliser trim can be used to neutralise...".
You need to go and read step 2 again. It wasn't completed, at any point after the MCAS AND.
What would disconnecting the autothrottle have achieved? Well you could set thrust to something more sensible and fly the aircraft.
You mean page 2 of the memo that gave specific operating instructions to crew? It even included a note (obvious to most with any common sense!) to put the aircraft in trim, then cut out the stabs.
