My guess is that he wanted (or was under orders) to get ejected for the next game to get rid of his yellow card, which would otherwise have stuck on for another two rounds of more critical games.

That's an interesting theory but it's definitely wrong. The card records of all players will be cleared after the group stage so everyone goes into the knockout rounds with a clean record. It's in the rules of the tournament (for this World Cup at least).
