Is your question suggesting MCAS and autopilot might somehow be improperly connected via software logic, contrary to original assumption that MCAS CANNOT trigger unless autopilot is OFF? After reading the ASRS reports of MAX pilots switching autopilot ON during flaps up climb followed by almost immediate nose downs (fortunately stopped by going manual), I have been wondering if one possible explanation could be that through an untested bug in autopilot logic, MCAS code (which was supposedly an entirely independent subsystem) was inadvertently executed within the a/p system. Just a thought, but thus far I haven't seen a good hypothesis for the rather suspicious behavior.
