This is exactly what I heard when I rewatched the incident over and over again. It clearly sounds like someone is yelling "stop" once during that onslaught, and immediatly after Palhares walks away with his hands raised.
Ofc Palhares should have waited for Dean to pull him away, but this at least explains why he thought he had won.
I really like and respect Dan Miller as a fighter and person, but I find his reaction after Palhares walks a way a bit suspicious. He gets up and walks towards the fence, his whole bodylanguage signals that he has accepted defeat. If he hadn't verbally tapped, I just cant understand why he didn't argue the "decision" or go after Palhares straight away. Only after Dean made it clear the fight wasn't over did he run over to engage.
Very tough fight though. Was hoping for Miller, and second round was painful to watch.
