Thanks. As I said, it wasn't really true for much of the Clone Wars. But there were definitely instances like the one you posted where a character clearly survives being shot.It's been confirmed on screen in Rebels time and time again that many of the Stormtroopers who get shot with blasters survive, and are just stunned/unconscious. Just pay attention to the bodies and you'll typically see motion. Now, I don't believe this was true for much of The Clone Wars, but that's beside the point.
Rex or Cody get shot by a sniper to the chest and the captain still survives.

But of course The Marylorian Armor allows Sabine to not give a **** about a headshot.
