If the Edo was released for all but Madara, wouldn't that mean that the chakra was released as well? Sent back from whence it came? Dan's chakra went with him, right? Mu's not ghosting around with his chakra, right? So, why do the two So6P relics still hold Ginkaku and Kinkaku chakra if the edo was released?

Now, even if you suppose that the relics are such good seals that the chakra is unable to escape to the afterlife, wouldn't Gedo need to digest the relics, thereby releasing the chakra to the afterlife, to become the Juubi?

What's the deal here?
