I was under the impression that odd and even altitudes (1000' increments) were assigned by course heading. I would expect a pilot to question an assignment to an altitude not "owned" for the duirection he is going.

The Tahiti controller had mistakenly told one plane to change altitude to match that of the oncoming plane, and only because the automatic crash avoidance radar told one to dive and one to climb did they miss by some hundreds of meters.
