I can see that, cappy and OTWO. Especially with regard to printing things generically so as to allow for future changes which is sort of my point. If they believed the overlapping thing was long term why not print it there...? Instead its gone from both the insight book and the revised greatest man book. I cant help but feel this signals a change is imminent, although i freely admit that there is some wishful thinking on my part thrown in...
_Morpheus: I don't think the change is imminent. I honestly think they're just glossing over the official doctrine to avoid anyone questioning it. If someone asks for details on the generation teaching, they'll direct them to the Overlapping articles.
It's also possible that it's just the writing department that doesn't agree with the "overlapping" doctrine and are stating things as generic as possible - keeping things "technically" correct to get approval and avoiding addressing the overlapping issue so as to not cause Cognitive Dissonance and raising doubts in the rank & file.
Again, pure speculation. But, as those of us that have read Crisis of Conscience, it wouldn't be the first time the writing department disagreed with official GB approved doctrine.
