Meh.  Wives tale.

The only reason to not drive on a tire in the other direction is if it
has a directional tread design.

For a directional, it has to stay pointed in the same direction - so
to rotate sides, you'd remount the tire the other side out on the
wheel.      (not uncommon to be done in staggered configurations
(smaller front/larger rear)

Even the asymmetrical designs can run both ways - they simply have an
inside/outside that must be adhered to.

You don't find a single tire manufacturer to tell you that you can't
diagonally rotate tires as long as the tread design accommodates it.

You will often find different recommendations for front wheel drive vs
rear wheel drive vs 4wd - but that's about trying to balance the
different types of tread wear, not about the tires themselves.     And
our old VWs - particularly those with swing axle rear ends - have
their own wear patterns to contend with.
