I failed.
But I think it might be simpler than that. The side moving upward into the electron rain has a higher net velocity with respect to an electron, compared to the side moving downward. It’s going to be harder to stick to something moving faster. The fast side is more likely to kick it away.
The side moving with less net speed is less likely to impart kinetic energy that’s higher than the binding potential energy, which increases the chance for the electron to stick.
Or so I think at the moment. I reserve the right to change my mind and decide this effect is too small to matter in the light of the morning, after a cup of coffee.
