But that doesn't really explain it.
Most jet airliners have the landing gear retraction axis (ie the trunnions) aligned for-and-aft. Ditto the bogie when stowed is aligned longitudinally.
So simple geometry would imply that the bogie wouldn't have any tilt when the gear is lowered.
But it does, and that's clearly by design and for a reason.
