I think that has to do with people that book him how there percieve his name to be. Just think of it as in his first name is Rakaa and last name Iriescience. But to my knowledge he doesnt change it at all its just some flyers say one thing and some day another. I think everyone knows him as Rakaa first and foremost and the last part is just a lil something to add to it....
