I agree that this situation is suboptimal. The second meaning has
nothing to do with a direction but with a sense of rotation. So, I agree
it should be dropped first, if any.

I don't agree. The uses of direction for forward/backward are in the
same magnitude of order as for compass directions. A factor of 2 is not
relevant. Both uses have their tradition and they are not likely to be
mixed. The compass thing has more of an absolute direction than the
forward/backward one, as it only specifies a binary feature relative to
another oriented feature.
