Whether it's a counterfactual you is less important than whether it's a symmetric version of you with the same incentives and preferences. And the level of correlation is not independent of whether you believe there's a correlation (like on Newcomb's problem and PD).
Incentives, preferences, and decision procedure. Mine are not likely to be highly correlated with a random hazer's.
This problem is roughly isomorphic to the branch of Transparent Newcomb (version 1, version 2) where box B is empty, but it's simpler.
Here's a diagram:
