I thought they were all of the "other sheep" when that WT article came out about "helpers" in 1992...and most of the current GB were helpers when that WT came out...and it said all helpers are of the "other sheep" hence why the current lot cannot be the second generation in the overlapping malarky because none of them were anointed in 1992 because they were all helpers then and the WT said the helpers were of the other sheep.
notsurewheretogo, there you go- not keeping up with the celestial chariot. Yeah, that's how I remembered it then too. And I would help you bring your thinking out of the 20th century into the 21st century as the light got brighter, but I don't keep up with the chariot either.
All I know is, somehow the helpers became replacement anointed for those that fell away. I think it works something like this: The G.B. notices a good kiss-ass "helper" and wants him on the G.B. because sooner-or-later, the old geezers die. They start suggesting he reexamine whether he is other sheep or anointed because Jehovah keeps telling the G.B. that this guy should be anointed. They are good kiss-asses, so of course they go along. Had they not, they would have been sent back to the "salt mines" of dishwashers and waiters and those that get printing ink all over their hands.
