I read the whole article and I have come to the exact opposite conclusion you have. Granted when we speak of intermod we generally are referring to UNWANTED signals being generated. But I think that should be obvious in this discussion.

Granted on Distortion being unimportant.

To me it's obvious the diode rectifies an AC signal creating a pulsed DC signal that's filtered (to remove the RF frequencies) to smooth the final resulting audio signal.
