Nope, it was clearly stated that the incarnates can meet Hagoromo under certain circumstances, what these circumstances are wasn't revealed, by part of it is probably being on the verge of death and the rest most likely having Hagoromo's chakra thanks to Hashirama's cells from Kabuto (Sasuke's case) or Ten-Tails' chakra in Naruto's case thanks to Obito and the Tailed Beasts.
