The only thing which was divided into Yin and Yang were the seals on their hands, the keys to Six Paths Chibaku Tensei. exactly.

By the way, if a transmigrant awakens Rinnegan, they technically have Hagoromo's chakra. Once Sasuke has Rinnegan and Naruto has SPSM (and both have, due to their transmigrant status, the genetic potential for them), they have hagoromo's chakra permanently.

However, Hagoromo's gifts consisted both of a buttload of chakra (Naruto and Sasuke spam high-level techniques and never run out until their final fight, after they lose the Seals) and powers. Powers stayed due to the aforementioned genetic potential, but the chakra gift left them. Their reserves are their own, upgraded reserves.
