I'm trying to stay out of this, but can't avoid mentioning that although
Cecil insists on only one Pref and one Pfwd, he has different criteria
for voltage waves, and requires multiple Vfwd and Vref. So there are
four directions for voltage, but only two for power?

It ain't rocket science. Everything flowing toward the load is Pfwd.
Everything flowing toward the source is Pref. There's no third term
because there's no third direction. The directional possibilities of
power in a transmission line = binary. There's no magic third term
pointing toward Alpha Centauri.
