Unless I've completely overlooked something, this circuit does not provide any clipping whatsoever. It does nothing more then hold the carrier alive just as the circuit description on the The AM Window says. It claims no clipping action at all.

W8JI carefully explains how splatter has nothing to do with RF cutoff and has everything to do with the rise time and fall time into and out of the of the cutoff point. When the transmitter is cutoff, there is no power and no interference. When the angle of the waveform changes abruptly and with sharp corners, you have splash.

To the best of my knowledge overmodulation causes interference that is harmonically related to the modulation frequencies and not RF frequencies. This places the interference very close to the fundamental frequency and means normal bandpass or low pass RF filters will not remove it. It must be done after the clipping of the AF.
