Cecil,

What reflected waves?

An equally valid description in steady state, after all the transients
have died out, includes a standing wave containing the stored energy in
the line plus a forward traveling wave carrying the energy that does
make it through the load end of the line.

No need to account for any mythical power in the reflected waves.

This description matches your quotes from Hecht and from Ramo and
Whinnery that I attached a few days ago.
