This means that all the remaining light (after the specular reflection is calculated) goes into the SSS calculation. So in this render you can see exactly what the SSS is doing.

Hmm... I tried that, and got this result. Clearly something is different somewhere, but it's too late in the evening for me to figure it out now. The proper render looks great (it's PBIV texture), so VSS is doing things right; but this isn't coming out as expected.
