You've been focussing on the most irrelevant part of my comment.

Nothing to do with being Polish in particular. Only that there is a connecting element that might help explain why these 3 decided to resign together on the same day.

All of them being from the same area is relevant. Them being polish is not relevant except to show that they were from the same area.
