He does so well because they were not expecting resistance at that stage.
If he had just kept walking, they would've kept following him while moving to surround him. He had the good judgement to start swinging before they surrounded him, catching them off guard and out of position.
It takes a few seconds, but they eventually surround him and he rapidly starts being overwhelmed, but it doesn't matter because he has already shaken their confidence. Every single one of them is now aware that they have fucked with someone who will fuck back, and even though they gained the upper hand at this point, they back off anyway because he has proved to them that he is not going to go down easily.
Same thing with any predator. Anything that actually fights back isn't worth the risk even when you're guaranteed to win.
In this case, if they continue the fight he's going to keep wailing on them until they actually seriously hurt him or murder him and then the police might actually do something about it. Might. But it's not worth the risk.
