We can clearly hear that Ricky’s radio to Carlos was “do not put him under pressure,” nothing else, and he didn’t, he passed him quickly and safely
Meanwhile Bryan tells Charles “Carlos has been told to not overtake, but is really close, he might be just in front.” Realizing what he says he immediately corrects the wording and says “he’s been told not to put you under pressure” when Carlos was already ahead
I thinks this miscommunication is the origin of the drivers getting upset about their communication, I don’t think Carlos did anything wrong
