The creators had said once that bending was a combination of spirituality and hereditary genetics. Even though Aang stripped Yakone of his bending, that does not mean that he suddenly wouldn't be able to pass on the waterbending gene anymore, somewhat akin to how Katara was a waterbender, but her parents were not. It just ran in her family. As for how exactly the spiritual side of it all works, that it rather unclear.
