I saw the interview clip on yahoo...
At first I saw it as 'he's trying to safe guard himself from any responsibility or threats of child support if they are his kids' the woman says they're not his, but he wants to make sure. Then at the end of the interview he switches motives and says he wants to help her, because the woman needs help. So, now the guy wants to be a father figure anyway? Whatever, its his life, if he wants to be a part of his ex's life in someway all power to him I guess.
