What prompted the statement? How was it derived? What is the Data referenced to prompt this speculation?
The DFDR includes two discrete parameters: Control normal law in pitch engaged/not engaged, and Altenate law engaged/not engaged (see page 107 of Interim #3). There is also an ACARS message to that effect.

Of some importance would be the record of airspeed loss, rate and value.
Airspeeds 1 and 3 are recorded and shown in Interim #3.

A more probable problem would be (...) AoA excursion WITH ROLL.
The FCPC's use the mean of AoA1 and AoA2 to eliminate effects of roll and sideslip.
