No, this action is totally okay if it was the Juubi itself, i.e. the sequence is following: Hamura/Hagoromo touch the Ten-Tail's eye with their seals > it transforms into the CT core > it's stripped off from all its chakra and becomes the Gedo Statue > this chakra is sealed within Hagoromo, while the Statue is trapped within a celestial body forming (the Moon).
