I agree with Jeff (is there a full moon?
)
If he'd said those things to you while you're on the way to your dressing area that's one thing. He said it in his office so you should leave it alone but his leash for the 2nd half becomes so short he'll need a microscope to see it.
He's doing that for a reason since he knows you and your partner can hear him. It's similar to when a HC says something about you to his AC or other bench personnel while you're right in front of him then when you turn around he says, "I wasn't talking to you." If someone wants to play that game that's fine but he should be prepared to deal with the consequences of his actions.
