I this comes from the legal departement.
Maybe it has to do with each congregation being a separate legal unit (I hope this is understandable, I don't know how to put it in english) and not to be directed by the WTS. The WTS and the GB seems to separate themselves from the congregations, and the reason is probably all those lawsuits.
They throw their COs and elders under the bus........that's sad for thos loyal company men.
