But he used Son Goku's Rava release in that mode, am I right? unless I'm mistaken or it isn't part of RSM O_o?

Now that I think about is it implied in databook that he can use chakra of any nature and he can quickly grasp it as from this statement: "it says that this is a technique that allows the user to quickly grasp the nature of Chakra with the skill of a well-studied, highly sensitive master".

He wasn't able to use it before he unlocked SPSM.
