I guess that is an important part of his self-identification,a person is proud of being a family man and wants to share it with the world. Alternatively this may be a signal for recruiters that a person is not willing to do a lot of overtime.
It feels to me like these american show masters, who get on stage and greet the people with a "hello, how are you doing" but since he's asking the whole audience, no one answers.
well played :D
