Has anyone not thought that most of those payment addresses that received the "double payment" is Nefario's own addresses?

I have had a teller give me some extra money before.  The reason why I give it back is because the till count will be off and that teller would have to makeup the extra money the teller gave out.

I don't see how this is not the same for Nefario.  He can go forward.  If he does not have any bitcoins left, he can start to release the assets without any problem to asset issuers and claim codes to users.  He can also be contacting all those he sent double payment and ask to receive the funds back, for those that don't he can make up the difference with his money, just like they do in the real world.
