It was a tongue-in-cheek reply, Roy. These problems always seem to end
up with a circulator in them at some point - clearly illustrating what
happens under entirely different circumstances. :-)

The circulator, lossless feedlines of unreasonable length,
Time Domain Reflectometers, TV ghosting, etc. are all tools
for illustration purposes. However, a Z0-matched system is
an ordinary configuration in ham radio and is easy to analyze
since no reflected energy is allowed to reach the source. The
conservation of energy and momentum rules dictate where the
energy must go in such a case. We can debate why the reflected
energy is 100% re-reflected but there is no question that it
*is* 100% re-reflected because none reaches the source and
there are only two directions in a transmission line.
