Yes navigating inverted is almost as easy with practice. Up / Down / Left / Right becomes relative to the aircraft instead of relative to the world around you.
So while this bug exists, being an inverted flying expert has some useful benefits 
Normally inverted flying is something fighter pilots train a lot at getting good at 
to dog fight maneuvers.
I wonder if fighter planes like the F22, have computers on-board that reverses the control scheme when inverted to make it feel the same for the pilot ?
