If we count a generation every, let's say, 30 years, that would make a total of 34 generations over the 1000 years between Indra/Asura and Sasuke/Naruto. Assuming that on average a person had 2 children, given that some of them died childless, that would mean over 1 billion (1 073 741 824 to be exact) descendants of either Indra or Asura 30 generations from them, and over 17 billion 4 generations later. Given that all of the main descendant clans became citizens of the Hidden Leaf, it's not that much of a strech to assume that Sasuke and Naruto are in fact their direct descendants.
