Disclaimer: I am lamer in physics.

I think the analogy shows that FTL (superluminal) speed exist and is
experimentally observed, this doesn't contradict relativity.

What contradicts relativity is _communication_ or clock synchronization
faster than light.

IIRC if you point powerful projector at the Moon and move it slightly,
this light on Moon will move FTL at least from your point of view. 
Jim's horse was something like this.

Check wikipedia for faster than light for more examples like this.
