It does, except when you lift your whole network gently and flip it
upside down.

You must be thinking of FDDI. Normally, tokens go round and round in the
2 rings, one clockwise and one counterclockwise, and go past each other
without ever touching. However, when they would otherwise cross the
equator, tokens reverse direction and switch rings. Sometimes, when that
happens, they collide and give birth to exotic MAC layer protocols,
which scientists like me study and write long monographs about. Thus
were such wonders as BRAP and MLMA discoverd.
