For info, the A330/340 FCTM that I just referenced defines flare law as follows. FLARE LAW: The control law is a smoother direct law. (FCTM Operational philosophy, Flight Controls)

The A319/320 FCTM in the same section reads - FLARE LAW: The control law is a pitch demand law.
The FCOM PRO-ABN for that failure mentions Direct Law for the A320. For the A330 it mentions when L/G down... MAN PITCH TRIM USE and switching to flare law occurs if AP is OFF. To me, as I was mentioning before, it looks like the airplane will end up in the same handling characteristics in both cases but legally speaking there is not "direct law wording" for the A330 so technically no correction.
