So the half with Minato was technically dead (but since they're spirits, they can't really die. Which is why they reincarnate in the first place).

Whatever material Orochimaru retrieved of Minato must still have contained some of Kurama's chakra, and so upon using Edo Tensei both Kurama and Minato were sealed in the same body.
