recovery from unusual attitude where low airspeed and high AOA
I sugest you are confusing Attitude with AoA, they are not the same thing. It is usual in practicing UPs to give the student a hight nose attitude with decreasing airspeed, if the aircraft is accelerated at the start of the manoeuvre, the AoA will be quite low because the aeroplane is actually going where it is pointing, upwards. When stalling, you entered from a power off level attitude.
