No, AP moves the yoke. With AP off, the flight director will give cues for what you selected. Never tried to overpower the AP, I always turned it off if needed.
And if autothrottles engaged would advance as the speed slowed to bug?
What about if the flight spoilers were extended?
You get an EICAS caution if the spoilers are cracked and thrust is above idle, with AT on or off. (B744)
I'm only guessing Boeing used a PID algorithm for thrust setting and as such would increase thrust if needed to maintain the set point, which it does. (B744)
