IMO, a rear spoiler is supposed to "spoil" air flow, and therefore increasing the local air pressure upon a surface up stream, to intentionally increase DF.
Maybe, but with only a quick glance, I don't see any real "spoiling" of air flow taking place in the pics, related to my earlier intuitive definition of what a spoiler does.
