There's no direct correlation, yes. If you took two executives (or really two people in any profession), one making 10x as much as the other, and swapped their positions, you would not see one position dropping to 10% performance and the other rising to 1000% performance. In all likelihood, they would both drop to 50-70% for a while and then stabilize to their original values.

Individual persons are not orders of magnitude more productive on their own, they're just in environments that allow them to be more productive, for example by giving them control over more resources.
