Turbulence caused a momentary excursion of "phase advanced" AoA beyond alpha-prot, and that put the FCS into alphaprot law (High AoA protection). That protection is lost in Alternate Law 2. I believe I have read on this thread that this particular logic has been changed as a result of the A340 AirProx incident.
