Interesting question. Jehovah's Witnesses almost pride themselves on the constant re-naming/rebranding of their religion. I have heard it stated on multiple occasions from the platform that they often consider this a safeguard. They will use this practice as a means to test those who are unknown to them and claim to be one of Jehovah's Witnesses as to whether or not they are active.
Case in point - I left before the new title "Congregation Overseer of the Body of Elders" was given to the congregation Presiding Overseers. If I walked into the local Kingdom Hall claiming I was from another congregation I might be asked "Who is you COBE (literally spoken as the initials or even pronounced "Ko-Be")? To which I would have to ask, "What is that?" In turn I would be dismissed as a non-Witness or an inactive Witness who hasn't kept up with "God's celestial chariot."
