No sir,
what I'm trying to say is that the green hydraulic system (Airbus loves colours) supplies the hydraulic pressure to extend/retract the gear. The Green system is normally powered by two engine pumps.....one on Eng #1 and the other on Eng #4.
If #1 Eng is lost due birdstrike, I believe the pressure provided by the Eng #4 pump would be sufficient to extend or retract the gear.
With that in mind, I, like you am also curious as to why a free fall extension was carried out.
