True. Further, all the same-frequency, same-direction signals merge. So,
as Cecil said, there are only two same-frequency signals on a
transmission line, forward and reverse. The interference pattern these
signals produce does not represent another signal.

So the claim is that the amplitude of the reflection being bandied about
is the sum of multiple reflections? I haven't seen any indication of
that. It appears to be simply the amplitude of the first reflection.
At least, that's the way it appears to me, the uninitiated.
