Agreed. Without decoherence, the cat would be in a superposition of alive and dead from the time the box was closed until someone opened it. With decoherence, it would be in that superposition for a very short time, the decoherence time, when it would be in state, |decayed>|dead> or |undecayed> |alive> before the box was opened, provided it was opened after the decoherence time. So, as I see it, decoherence just moves the "collapse" earlier, before the box is opened, and does not resolve S's problem with superposition. The cause of the problem, or paradox if you will, is the superposition interpretation of the radioactive source.
