Ayuh.  It's a head-bender, so solve it graphically.  Wrap two paper
slips around the ends of a pencil, use one hand to drive it and the
other to resist, mark arrows on each in the direction of the force
your hand is exerting.

Flip the pencil end-for-end -- no change.  Use your other hand to
drive the pencil (with or without flipping it -- now you're working
against the arrows, so swapping side-to-side works if you can.  Now
flip the paper slips around on the pencil -- now you're pushing with
the arrows again, so that works too.

So...end-for-end does nothing.  Flipping the joints on the shaft and
replacing it on same side works.  Swapping the shaft to the other
side works.  Flipping joints *and* swapping to the other side negates
the effect.
