I dont know if you guy have a "special" model 320, But as per our FCOMs for the (319,320,321) 3.02.34 below is a snipit,
Both RA FAULT
When LG down: Direct law. At landing gear extension flight controls revert to direct law in Pitch as well as in roll (see direct law procedure 2.02.27)
Dunno if that will clarify, But I agree a dual Ra fault in the Flare would not be a fun situation!
