i'd say that young madara is a clone created by Orochimaru, seeing as how Orochimaru always wanted the sharingan it makes sense to try and clone him but couldn't control him. also when madara cuts off one of his arms you can see (below) he's made out of some white goo similar to zetsu's body. whenever i see white goo i think orochimaru and his white snake obsession. only problem is if that was true, young madara probably would've killed orochimaru, though i've never seen him go on offense, all he does is avoid minus that one kick to naruto's face. he also did tell the kages he was only a shell of his former self, which would explain him not fighting. http://manga.animea.net/naruto-chapter-475-page-10.html http://manga.animea.net/naruto-chapter-475-page-11.html i saw people get really serious over this, but don't attack me or anything, these are just my thoughts.
