Is this "clarification" related to the pressure being put on them by governments about the disfellowshipping and shunning of children?
I'm sure it is. I have seen many "adjustments" made by the WTS, driven by a negative legal experience because of treatment of df'd jws. In the past the WTS announced people as being df'd and name the specific sin, in an announcement from the stage at the "service meeting." It was also announced at other congregations the person had attended in the past in the area. They finally adjusted it to "is no longer one of Jehovah's Witnesses."
