crediting "reflected energy" for the heating. And based on similar logic.

One can mentally install a one-wavelength piece of lossless
transmission line between the source and load which will
allow one to analyze the interference patterns. Constructive
interference toward the source certainly can cause heating
of the source in perfect accordance with the conservation
of energy principle.
