I don't know the answer to your question, but I have always assumed that each one (except the first) is triggered by a signal (IR?) from the one in front. If the sequence ran in the other direction (i.e from back to front - not very useful) the next could pick up the light flash from the one behind, but I'm not aware of light being shone on the next one behind.
