How did he know he was going to have an MCAS event? He was dealing with a stall warner that shouldn't have been warning.
Auto pilot was also a 'known' protection against MCAS as mentioned in one of the safety reports a page back or so.
Had the auto pilot stayed engaged another couple of minutes we might not be having this discussion.
Btw: I am not faulting the auto pilot (probably the only thing that is mostly innocent) or agree with decision to engage it given stick shaker etc.
