Aug 2, 2015 at 5:37 comment added Timaeus If you say that they have relative velocity that presupposes that they measure equal and opposite velocities relative to each other. But it is by no means obvious that just because you measure a different observer at two events with an average velocity of v that that observer will measure you at an opposite velocity. And velocity addition is also a fairly nontrivial result.
