Again, I agree with Zeke!!
It was a pilot mistake......
Why he disconected the A/T so low, the Fcom say you shouldn't do it below 1000ft RA if not for a Goaraound and if he did that the Clack Clack would have happend earlier..
at 12.45.25 he disconected the A/Thr and onlu at 12.45.34 he advanced the thrust lever....
The A/T in the airbus is doing a good job as long as the input are right (wind etc..).
