Why would the room being successful reveal anything useful? Why does it matter if a program is executed on pencil and paper or electronically? The thought experiment does not bring any novel insights and just misdirects the reader by focusing on the human.

You could execute the Strong AI program on any Turing complete system. Asking if the human understands Chinese is just as absurd as asking if a universal Turing machine understands Chinese given the same program. The machine just follows the instructions given, the philosophical questions reside entirely on the side of the program and the execution of it.

I think you have put your finger on exactly what is at issue: it does not matter whether the program is pencil or paper or electronically. It's an analogy. The point is that we do not (says Searle) impute understanding to the person in the room, therefore we should not impute understanding to a computer running a program. But Strong AI requires us to impute understanding; and this is exactly what is impossible. Therefore Strong AI does not exist. I take that to be the force of the argument.
