Joey, that elder needs to read Ray Franz's In Search of Christian Freedom. Franz, of course, was a member of the Governing Body, so he was in a position to know.
On pages 152 to 164 he explicitly deals with the widespread perception among Witnesses that anointed JWs pass on their thoughts to headquarters and that these are then translated into doctrinal shifts. Franz says there is no such process, and that letters from anointed JWs are treated with no more interest at Bethel than are letters from anyone else.
The WTS has explicitly said no global network of anointed Witnesses exists to reveal new spiritual truths, and that those members of the "slave class" outside the Governing Body are not consulted when making decisions. For references see "The Faithful Steward and Its Governing Body", The Watchtower, June 15, 2009, page 24, and "Be Obedient to Those Taking the Lead", The Watchtower, September 15, 1989, page 21, paragraph 5.
