I don’t know how to reconcile the Watchtower statement that GB helpers are from the other sheep, with the fact that the two new appointees, who are described in the announcement as anointed, (plus Paul Gillies, also rumoured to partake) are listed as helpers in the Watchtower article. It appears to be a contradiction
I had someone explain it to me as, your appointment to the governing body IS your ANNOINTING. I don't know if this idea comes from Crisis of Conscience. As i recall the person saying this to me may have referred to it.
