Electricity moves at the speed of light.

Electron drift is quite slow - a few metres per second. Electricity is
faster for the same reason that you get a tennis ball pop out the back of
the tube the same moment you push one in the front - i.e. it's a different
ball - but electricity is not electromagnetic radiation, surely? So I'm not
convinced it travels at the speed of light. Got any authoritative refs?

There wouldn't be time
for the rotors to shift between reaching the reflector and going
back through the rotors.

That, at least, is certainly true.
