Seems you've lost a couple of terms in there.

This is why, in general (using my definition of general), superposition
does not hold for power. Those extra terms get in the way.

I suspect that Vf*Ir and Vr*If have absolutely no physical existence.
Light waves traveling in opposite directions have no effect on each
other. Why should RF EM waves traveling in opposite directions have
any effect on each other?
