If A and B are indistinguishable, then there is no functional difference between the two. If the Turing test can be passed, in any of its instantiations, then that's an important thing.
You can't say that the Turing Test has been refuted without defining what you would've wanted to use it for in the first place. I use it as a practical example of functionalism, ie If something appears, to all intents and purposes, to be X, whether or not it is 'truly' X is not relevant.
I am tempted to post links to Twin Earth discussions, but I'm not sure that I'm feeling that cruel today;)
