I've always suspected the King of Hell is involved in the creation of the fake/reflected dōjutsu. Like it swallows up the corpse or summoning animal and then spits them back out with Rinnegan. It's clear those Rinnegan aren't the same as the real things, but they do appear to have some power. The Deva Path uses its Rinnegan to see the barrier around Konoha, for example.
