The pilot made a nose down input.
That nose-down command between 2:10:16 and 2:10:50 reduced the vertical speed from 7000 fpm to 700 fpm and AoA to (less than - in my simulation) 4 degrees (reducing v/s implies less than 1g, hence reduced AoA) - no stall warning at that point. Then a nose-up command must have followed calling for about 1,1 g and an AoA that exceeded the stall warning threshold, and ultimately the stall AoA. The 1,1 g increased the vertical speed from 700 fpm (to about 2500 fpm in my simulation). Look at BEA's "3D view" for the partial level-off followed by a steepened final climb just before the apogee. The airplane stalled before the apogee.
