As a proxy variable, it's a proxy for things that were already true, they just hadn't realized it yet. It's like how there's a lot of turnover after bonus season. The bonuses aren't the reason they're coming/going (though they're often shaped significantly by the real underlying reasons they're coming/going), but they do effect the timing of their coming and going... because that's the point where it becomes impossible to ignore the underlying reasons for the turnover.
