1) It's somewhat problematic if leaders regularly make very strong, emphatic statements, specifically saying that this is not an ordinary decision but rather one that will never be changed under any circumstances, and then change their minds.
2) If they're going to do that anyway, then maybe that should be explained to newcomers, since their default understandings will otherwise be wildly miscalibrated.
You seem to be arguing about something else, not entirely sure what, and I don't have much to say about it.
