My theory actually came from a deleted scene from Avengers: Age of Ultron. It is sort of an extension of Thor having the Infinity Stone vision. In the scen, he is possessed by something that sort of explains what the Infinity Stones are. One of the things the voice says is that the Infinity Stones cannot be brought together nor seperate.

I know it's from a deleted scene, so it's not canon, but like I said before we see the stones following eachother around the universe, so I don't think it's an entirely ignorable quote. I sort of hope they bring the quote back in Avengers 3 to make it canon and as a way to explain what seems like a huge coincidence.

As for the Asgardians and sorcerers knowing the others possess stones, I'd say it's possible. Wong does acknowledge that the sorcerers know what Infinity Stones are, and in the mid credit scene we learn that the sorcerers know the Asgardians exist. Plus there was the line about the sorcerers defending reality, and with a Reality Stone and the other stones that manipulate other aspects of reality, I'm sure the sorcerers have been at least trying to follow the stones' movements.
