Sorry for the delay in responding, just now noticed your reply.
However looking at your garage too me it appears the transmitted pulse of light has left the garage however is the returning incident pulse that is returning to the garage at 300 times reduced speed.
The garage analogy is a very weak one. You're reading far too much into it if you're looking for actual correspondences to light pulses. Its only purpose was to point out that you're observing a secondary effect, not an actual sequence of events that indicate superluminal velocities.
I don't think I can add much to what I said before. I again refer you to all the places in the article that make clear that c has not been violated and that relativity is intact. I quoted these in my
