No, you are not reading the graph correctly. Perhaps you should read it together with
another graph that shows vertical speed and altitude.
Per BEA the airplane stalls around 2:11:00, after AoA exceeds alphamax and then approx. 9 degrees and continues increasing as shown in the first graph. At 2:10:30 the vertical acceleration reduces to less than 1g. Vertical acceleration above/below 1g is the rate of change of vertical speed, which is 7000 fpm at that point and starts reducing to 700 fpm.
