Can't speak for French/Spanish footballers, but here they force feed you certain rules and I'd bet many Norwegian defenders wouldn't know this rule. In fact I could ask a couple of the guys I know who play here and I bet one of them wouldn't know.
Simply a lot of rules very rarely come into play and you don't have to worry about. Rules you might have heard about, but never cared about and actually remembered, learned.
We'll never know if Mathieu knew this one or not, but we all can agree on that he played that really stupidly.
