They both can be given as yellows, but it's the sort of thing that when you know another yellow is a red, it's too harsh. Refs often let them pass. His first tackle was barely a yellow, while his second probably was. In this case, the ref fucked up for the first one. It's his fault not Pogba's.
Given that, Pogba should have chilled out after the first yellow, it's a sign of immaturity for him. There's no doubt about how talented he is. He will be great for us and France. He was amazingly confident today, and you can easily feel that he's been playing at this level for 15 years. Extraordinary stuff.
