I suspect that Felos' relatinship with ethics is similar to his relationship with truth...useful when conventient, usually as a standard to hold OTHER people to.
Felos has that same quality of telling "little boy" lies that Clinton so loves to do. Here, I think what he said was (something like) "Michael hasn't sired any children," and what he may mean, in a little-boy evasion of the truth, is that MS is merely the sperm donor, not the legally responsible, marital father, or "sire."
This is one possible explanation, anyway. Who can say.
