Your're right, my bad. I kind of wish there was a filler about those old times. But if you scroll up to when I first talked about it and my first reply, I did say that I was unsure about him actually calling it a mutation, but positive that he was not familiar with it.

Now out of curiosity, in the original tablet that he made, was it ever mentioned what was written in it? If there was and it said anything about joining both his son's for his eyes, then it could help settle this.

If he had the Sharingan before he Rinnegan, then he wouldn't think that they would need to combine to gain his eyes, instead, he would think that the sharingan would evolve into the Rinnegan with Shinju or something of the sorts. Like it supposedly happend with himself.
