Did he really say that she had the Sharingan? Positive that it isn't a translation error or something along the lines? She never had the Sharingan, her eyes were white before she gained the +1 from eating the fruit, and after the fruit she gained the Rinne-Sharingan.

As I see it, Kaguya had the Rinne-Sharingan and the byakugan, her bloodlines got divided and Hagoromo gained the Rinnegan while his brother gained the Byakugan, then like his mother, Hagoromo's power go divided once more between his two sires.

After Hagoromo, Indra's sires also got e lesser amount, and the need to gain the EMS to retain their abilities.
