Why the first stall warning?

I'm puzzled by the initial stall warning which occurred only 5 seconds after the AP disconnect. It seems spurious, and the pilots clearly notice it and then seem to attribute it to the 'loss of speeds'. Which perhaps created a mindset in which the significant stall warnings at the apogee (?) 40 seconds later were seemingly disregarded. Did the PF make SS inputs sufficient to cause the initial warning? Or what?
