Oof, that picture. I didn't realize Tony Morris had let himself go...
I agree that they now have an issue where they cannot go back without confusing the rank-and-file. Remember that all of these changes and 'clarifications' are usually accompanied by breathless expressions of how the change is a clear example of Jehovah's loving guidance towards those that he does not wish to see perish. The pronouncements are usually followed by the joyful expression of "how wonderful it is that Jehovah provides perfect and thoughtful guidance as we march towards the end," etc etc.
At some point, if you are laying it on that thick, it's not easy to roll it back without leaving people wondering what just happened. The GB may get away with claiming fallibility, but that doesn't mean they can always get away with yanking the rug out from under everyone's feet.
