The fact that the Stall warning came back after some Nose Down Input due to the IAS exceeding 60kts again also points to the fact that the control authority was not really lost
.
It only points to the fact, that airspeed was not stable below 60 KIAS (if that speed was the real one and not some falsified indication by pitot icing or high AOA).
The BEA note seems to me to strongly imply that the ND input did in fact cause the AoA to improve as would be expected, hence the input did have some effect.
Around fifteen seconds later, the PF made pitch-down inputs. In
the following moments, the angle of attack decreased, the speeds became valid again and the stall warning sounded again.
