petshoo, absorbtion such as this is regularly referred to as SSS in 3D apps. Most people consider it as such, because true physically correct SSS is extremely slow to calculate. It's not really a novel tactic to advertise it as SSS in my opinion.

Some render engines, like Vray, require you to use GI in order to process physically "correct" SSS. Yet, in the end, only a highly trained eye would notice the difference between real SSS and fake SSS (if it's done right). I don't see the big deal over that really.
