No.. this is not about the autopilot. The suspicion (which is only a suspicion so far) is about another system called MCAS. Roughly speaking (specially because I have not enough knowledge to speak on this regard with confidence), this is meant to help pilots prevent a stall. The MAX family has more powerful engines, and they are a bit projected ahead under the wings. This makes the plane susceptible to point its nose up during full throttle, which could lead to a stall. This system shouldn't be confused with the regular autopilot. It plays a completely different role and, the way it's designed, it should engage only under very specific conditions.
