Welcome to OCR.
As far as I know, ReMixers on this site aren't required to follow the same goal as the original composers. While the original composers have to create a tune specifically for the game's scene, ReMixers here are allowed creative control of their own work to make whatever stylistic choices they want. They aren't making soundtracks for any videogames when they start working; they're interpreting the music the way they envision it in their minds.
Edit: JJT beat me to the punch . No need to be harsh, buddy. He just made a mistake.
