Bulley,

This is true and it matters not if the axle, in toto, is flipped end-for-end
during its migration from side-to-side.  The result is the same.

The pencil twisting proves nothing and may only spawn more emaciated
reasoning because flipping the pencil end-for-end, changing nothing else,
results in the noted reversal.  Also, switching the pencil from hand to hand
without flipping it end-for-end, does not change its relative rotation.

Perhaps, twisting a popsicle stick while keeping track of what is the driver
and what is driven would be illustrative of what's happening.  The change in
the lay, twist, handedness, or whatever you want to call it, of the helix
formed by the popsicle stick when switched from side to side, should turn on
a few light bulbs.
