That's basically a breakdown of the analogy.

If you want, you can forget about recording and tapes. Assume there was another person (unaffiliated with Mick or the reporter) standing next to the reporter while the experiment was being conducted. The rest of the story can stay the same. Mick also does not want this person to become convinced that Mick knows the secret.

Per the original story, this second person cannot know whether Mick coming out of the path that the reporter announces is a genuine display of Mick's ability or simply a collusion between Mick and the reporter. But if we go with the plan to observe Mick going in one path and out the other then this second person can become convinced of it.
