Ed, et. al.,
Half correct. Swapping axles left-for-right reverses the load-bearing
to the opposite side of the CV, using a previously-unused bearing
surface.

Swapping axles end-for-end does not do this, nor does it undo any
gains made by the above swap. Swapping end-for-end is completely
optional and neither gains nor loses anything.

See my lengthy description, elsewhere in this thread, of how to visualize this.
