An explanation from Airbus presentation on dual engine flame out with RAT powering the Green system says With recovery of engine1, green and blue systems are recovered the ECAM continues to show landing gear gravity extension to cover both cases of engines recovered and not recovered because gravity extension has minor consequences like nose wheel steering loss. LGCIU1 stops nuisance warning from GPWS. It recommends to follow the ECAM but technically it appears you could lower the gear normally. I am not a 330 guy but happened to see the presentation because it explained the difference with A 320 system.
