The nose doesn’t have to go down as much as at least have a slight reduction in back pressure. Minor unloading has a big effect on AOA. Even at .95 G, which is barely noticeable, the plane will fly at less than it’s expected stall speed.
On the 727 it wasn’t a shock to get stick shaker if you were flying at the minimum flap speeds, especially while turning even using the increased minimum flap speed required while turning. Slight roll out, or slight back pressure reduction, and the stick shaker stopped. Completely unnoticeable by passengers.
At low altitude, in normal flight attitudes, minor AOA excursions require minor adjustments. At altitude, with more significant AOA/speed excursions, the airplane will need large corrections in AOA with resulting larger pitch changes.
