Maybe they sealed her physical form in the moon but extracted and/or sealed her chakra into Hagoromo at the same time or right after wards. As we saw the tailed beast were freed by the process of her sealing so maybe that happened as well only in a more fused form the first time around and proceed to seal that mass of chakra into Hagoromo. Later on near his death his split the chakra up and gave the split chakra their on personalities/abilities/and names.
