They do NOT "truck along and then suddenly decide to
interfere". Such nonsense is just a strawman presented
for the purpose of obfuscating the technical facts.

The two independent waves are generated at a physical
impedance discontinuity, the Z0-match point, and are
immediately canceled at that point. The energy in the
canceled waves is redistributed in the only other
direction possible in a one-dimensional transmission
line.

Exactly the same thing happens when the external
reflection is canceled by the internal reflection
at a non-reflective 1/4WL thin-film coating on
glass. Quoting the Melles Groit web page:

"In the absence of absorption or scatter, the principle
of conservation of energy indicates all 'lost' reflected
intensity will appear as enhanced intensity in the
transmitted beam."

i.e. the energy re-reflected at the Z0-match joins the
forward wave toward the load. The conservation of energy
principle will not allow any other result. Dr. Best's
phantom waves continuing to flow toward the source with
zero energy is just a wet dream.
