Forget the video and look at the initial adsb data from Flightradar that has been posted on the aviation safety networks webpage:
Graphic - Aviation Safety Network
A stall, recovery and then a second stall
It's worth pointing out that the data track shown there is for the last minute of recording, with the variations in about 30 seconds of a time frame.
Stall recover and enter a second stall in under 30 seconds, in an A321?
