If the rules found in the links are acceptable, I could agree that
energy be allowed to enter the connected circuitry. I think we will
find that the returning power from a reflected wave is either completely
reflected with no change in energy, or adds to the voltage, thus
increasing the current flow and power contained in the system.

I think you are on the right track, Roger. Another way of
saying it is: If the principles of superposition are used,
the superposition must necessarily be implemented. It appears
to me that the principles of superposition are being used but
the results of the ensuing necessary superposition are, for
some ulterior motive, being completely ignored.

When the superposition interference patterns between the source
waves and the reflected waves are taken into account, everything
becomes perfectly clear (including the deliberate obfuscations).
