This is puzzle that is going to have an interesting answer. I'm following a rabbit's warren that leads me to believe that the hydraulic pumps at idle can't pump enough volume at idle to pull both legs over center simultaneously and that there is something about the right leg (placement of the cylinder?) that makes the right leg easier to pull over center than the left leg. Once it comes over center, the resistance is a lot lower on the right side, so the left leg won't come over center until the right leg fully retracts.

This is a question I hope I NEVER find the answer to on my 500B. That
being said, I've heard of gear retracts happening on the ground. I'm
certain that ONE engine by itself makes enough pressure to retract the
gear at idle, as even during warmup at low RPM, my hydraulic system is
steady at 1,000 PSI regardless of steering or flap actuation.

As far as right vs. left, I don't know the answer to that one...
