He has to use his chidori on from the seal he has on his hand. He used it back and forth when fighting with Madara. Even Kakashi used it some how when he gained Obito's powers.
His seal was on his left hand and that's the hand he always uses it with, Sasuke is left handed. He used it once against Madara and it was black but after that he used it several times and it was always blue.

He isn't willingly infusing the Rikudou Chakra into his Chidori.
