And you have done an excellent job of doing so by providing
an explanation that refers only to forward and reflected
voltage and current. Not a mention of "reverse power" in
the explanation..

The forward voltage is in phase with the forward current.
The reflected voltage is in phase with the reflected
current. Vref*Iref*cos(0) = reflected power
