I don’t know shit about children and I have no education in the matter. It sounded like a good rule of thumb to me that if you don’t address the feelings and frustrations of a misbehavior child and give them an alternative method of expression then they’re either going to get more clever or more withdrawn. I suppose you can’t go “how do you feel?” as they try to carve into the wall with a knife, so it’s like a flowchart of

stop them from being a problem -> give them a space to cool down (preferably one that is soothing to the senses) -> ask them about what made them feel the need to lash out -> put them in BJJ classes -> start them watching One Piece

I’m not sure about the last two steps, honestly (they might need to be the first two steps).
