It's like a rear naked choke:

Taking a punch across the chin pushes your chin and in essence pulls the rest of your head leaving the brain to hit the inside of your skull. As a defense mechanism the brain shuts the body down.(From what I understand, I'm no scientist). But both have nothing to do with blood.
When you sink it, and you opponent passes out before he can tap, you have not strangled him per se but rather caused the brain to signal a "temporarty turn off" until the blood starts to come back up the carotids. The chin shot, in the same way, rattles the brain inside the skull and causes the brain to "turn off." The shot to the chin in boxing can be a killer as has occurred throughout the years in sanctioned boxing but death froma rear naked choke would take several minutes.
