The OP confuses how WT directives are interpreted and applied in different countries that have different cultures with a clear top-down mandate.
Anthony Morris is a representative of the Governing Body of Jehovah's Witnesses. They assert that they are the leadership of the "visible part" of Jehovah's Organization on earth. They regularly talk about this being an "international brotherhood."
What any GB member says is meant to be a directive for all JWs everywhere. Clearly, some JWs are more literal in obeying the "Faithful and Discreet Slave" than others. But this does not change what the GB intends.
They want everyone to obey them, even if what they say doesn't make any sense.
