Let me guess, you read VIZ MEDIA? If yes, the translation from VIZ Media was incorrect compared to the original.

In the original: "一度仙人化しただけはある...", which roughly translates as: "...you once made the Transformation of the Sage..." VIZ Media: "Since you′d been in Sage Mode once..."

It's obvious that Obito used to be Jinchuriki Ten-tails, which means he used to be Sage of the Six Paths, so now he uses sage power. Obito himself said he was the second Sage of the Six Paths when he was Jinchuriki Ten-tails.
