The Berlin and the Rossolimo can lead to similar structures. Team Carlsen has obviously made the decision that they rather want to defend it with the bishop on g7 than on c5. The game proves them right, because black is already better after move 16. Failing to convert this advantage sucks, but it’s even worse for Team Caruana. Their whole preparation got neutralized and their guy got tortured for 115 moves to finally escape with a super lucky draw.
