He's (understandably) over-paranoid that any unnecessary pressure to Bagnaia is unhelpful. Bagnaia can lose 5 points (finishing 2nd), or worse, crash. I bet if team communications were allowed, he would have been yelling "dont you ******* dare get near him!!!"

This is why it was a mistake to let Miller go. He knew his place on the team and would have (continued) to make an excellent #2 team mate and tail gunner. Having two riders racing for the win/championship is like shades of Rossi and Lorenzo all over again. No clear hierarchy with both riders tripping over themselves battling for Alpha.
