Wait, I think I already understood Thekillman logic, that's why I came to some kind of explanation. Though there are inconsistencies with Edo Tensei restoring a foreign material (like it's said in the article, Hanzo retained salamander's poisonous gland while Madara lost Hashi's cells he implanted during his lifetime), we can surely say that Rinne Tensei shouldn't destory the organs of Edo body which are "living", i.e. as Thekillman pointed out, Kabuto added real cells of Hashi to the "dead" reanimation body of Madara. Rinnegan would be restored as well only in the case it had formed from the "living" eyes, i.e., for example, if Kabuto implanted real Sharingan eyes into Madara, the Rinnegan developed from it would've been as real as Hashi's DNA face.
