That was just a cheap little trick to make material-based AO vary its effect based on which way the surface faces with respect to up or down. This was compensating the AO shadow to be less strong when the surface faces the sky. This isn't much help for determining where sub-surface scattering would pass through a surface and bring light from the lit side to the shadow side of a terminator (shadow edge).
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
