No, the concept here is that it pinches you jugular veins slightly, this builds-up some extra fluid around the brain, and thus the effects of a blow/shock/sudden stop cause less movement of the brain inside the skull. Basically what rams and woodpeckers bodies do to avoid concussions.
It almost sounds to simple to be true...
