The TMO is bound to answer the question asked by the referee. It's not an opportunity to expound on whatever they like.In both of bdp's yellows, ayoub really let Poite down IMO. Not defending Poite but a shred of pro active comment in the first situation from the TMO, should have got a proper decision. Either a penalty for offside or not. Think you could probably say the same about the poor communication between the officials in the second instance too.
Poite specifically asked Ayoub about the foul play AFTER the tackle, and made it clear he had decided on the YC already. It's not the TMO's place to start telling the ref what else he was wrong about.
the second YC seemed fair enough - leading with your elbow as a fending technique is clumsy and dangerous, and shouldn't be encouraged. The communication was fine - he asked Ayoub, and got an answer.
Without Poite's error on the first, the RC fiasco doesn't occur.
