Counterfactual correctness is needed as part of the computational supervenience thesis in order to forbid supervenience on recordings. Physical supervenience is something observed. Again, in order to prevent supervenience on physical recordings, actual physical counterfactuality is required - which is basically the quantum nature of physical reality.
