I've seen similar cases. I think I've seen 2 total where the fighter was more aware than the referee that his opponent was out. I can't remember who was fighting but one was a submission and the other was a strike from the mount, which took 2 punches and the guy was out. It was one of those moments where the fighter looks at the referee as if ask "what are you waiting for? Are you going to call the fight?" while the referee is just waiting for an onslaught of punches.
A guy called big show famously kicked the ref for that.
