The entry about the Otsutsuki Clan, Hagoromo, and Hamura also left out the mention of Hagoromo being the Ten-Tails' Jinchuriki. So it didn't explain everything, so it most likely didn't mention that Hamura didn't leave immediately after. He most likely had two sons, who's descendants became the Hyuga, Kaguya, and a possibly unknown third clan. Then he and the rest of their clan left and went to the Moon.
