The initial pull up immediately after AP disconnect IMHO was because pitch was 0 deg, altitude descending. For some reason his 2/3 deflection pull up maintained a level altitude for a number of seconds (downdraft?).
Subsequent pull ups IMHO were because he saw the red and black
barber stripes (low speed stability protections for stall only showing in ALT/DIR LAW) on his speed and mis-interpreted as the red and back
horizontal striped ladder of overspeed. The actual speed showing as being low - but he understood speed had failed. In normal law the low speed bar is amber.
Happy if someone can debunk/support my speculations.
