I just drive - at 175' and 108 kts you're not doing much flying. AOA will be limited by the aircraft, you're in charge of roll, and that's it. Guessing that AOA limit, or stickshaker, kicked it off based on the wording of the report. It states the a/p "disconnected" without any inference of human intervention.
Mr Spotty M - Yes, a/p off and maintaining airspeed is critical. Below L/D speed(basically approach airspeed) gliding distance goes down rapidly, and at stickshaker speeds, or close to that, there will be no airspeed available to flare the a/c to reduce vertical impact loads.
