An application I used to deal with was similar, but with a somewhat quirky developer, who would deliberately flip between positive/negative confirmation questions, e.g.:

- Confirm this is correct? (Yes=F1, No=F2) - Would you like to make any changes? (Yes=F1, No=F2)

And maybe sometimes flip the yes/no F-key assignments as well.

In theory this was done to force users to read the question and pay attention to what they were doing, in practice, users just memorized the key sequences.
