@Lorenzo VonMT, Oro still couldn't use any jutsu with hand seals needed, i.e. most of those he knew, even after hosting a new body. It's not until his arms were retrieved from Shinigami's stomach (along with the souls of Hokage) that he truly regained their use and his jutsu. With the body switch, Oro only escaped from the rotting effect, but not from the rest of them.
