I think it works out fine here. You have one path through all lives, you can't be adam and eve at the same time but you can interact with yourself as either of them at some point in your path. Of course i think original sin should come pretty early in your path ;)
I think it's a fair question. But if God can be omnipresent, omni*. Then soul, which according to the story is a God in making can also have those attributes.
