Well, the guy doesn't own a cell phone. He was probably convinced by a publicist to do this "new type" of interview, and wasn't filled in on the details. This is an old guy who has probably done 100's of junkets where you sit for one interviewer after another, and if you don't control the interview, you end up not promoting the movie. You give the same canned answer to 20 different regional stringers, and if anyone starts going off message, they lose their credentials for the next one.
So put yourself in that headspace, and you sit in a room with someone on a computer who is going to read you unscreened questions and transcribe your answers unfiltered. The mere fact that he felt the need to even say "let's stay on the topic of Rampart" tells you that he was entirely out of touch with what an AMA was.
He could have simply ignored the questions about his sexual relationships, and not responded to anything related to Rampart. When none were asked (because lol, Rampart), someone in the room should have explained to him that it was an open forum to discuss anything, and trying to control the room would be met with backlash.
So yeah, to answer your question, "all of it." He didn't get it at all. But I don't think that's entirely his fault. He's just an old guy who is out of touch and likes to sleep with prom attendees.
