I actually didn't see it that way at all. I got the feeling that Garner, at least, didn't have a clue who he was. They were mid-interview and suddenly he was walking between them and the camera and then he's leaning over Garner, hugging her, and kissing her on the neck like they were old friends. She called him "That man", which indicates to me that she may not have even recognized him.

I don't have a stable connection and can't seem to get his radio interview to play, but what he said about it the next day, unless here was a whole lot more, doesn't negate the fact that he somewhat rudely interrupted their interview and was a little more physically close with Garner than she felt obviously comfortable with.
