Let's admit that, but the meanings of W1 and W2 are cultural.
How do I know something turns clockwise --- that is, how do I explain
it to some distant alien ???
If I say that the rotation vector is some Z which is (X x Y), then I
must explain how to carry the vectorial product in such a way that I
notify that the Z direction is the one of my middle finger when my
thumb plays X's role, and my second finger Y' role, with my right
hand, for instance...
Which is totally untractable for a alien living in Andromeda, or in a
mirror-reversed world.
Thus, this explanation is CULTURALLY biased.
Another explanation invoking the rotation direction of an ORDINARY
clock, or of the Sun in MY hemisphery,... would be of course cultural
too...
It appears from your statement the you're making the obviously invalid assumption that these peoples would have a common language with us. It is a near certainty that not only would any beings we encounter /not/ speak any of our languages, would likely not share any of our values, and possibly not even experience events in a similar manner to us. It goes without saying that in order to have successful communication with ETs, we would have to first find and then build upon common ground.
