So switching seats during the flight would have solved the problem?
I'm not a pilot, but if the controls are linked -- why would the plane need to know where the pilot is sitting (or even have a switch for it)?
(Any 747 pilots reading? Can you please fill in the gaps for me?)
I said 747 because I was thinking Boeing at the time, and that was the first of their aircraft I could think of!
I was also thinking something smaller like a Cessna might not have the same setup because they're used for very different things (the air travel equivalent of a bus vs. a car).
