It doesn't matter. At HF wavelengths, the last photon is not going to
have an appreciable effect ( but maybe at gamma-ray wavelengths). The
collapse of the probability function indicates that if one runs a
large number of trials, n% of those very last photons will be
reflected and (100-n%) of them will be absorbed. That probability
function has never been proven to be wrong.

I have no idea why an otherwise knowledgeable individual could be
argumentative concerning this subject.
