"This is definitely not JW terminology. Are you referring to a Governing Body member?"
Sounds like he's referring to the WTS Board of directors. What has been suggested as the 'puppet masters' to the GB. The GB are the puppets that the Board of directors actually control. I've hear Mike on the Kim Mikey youtube channel refer to them as 'such'.
Or, one of the GB members actually may have been involved in a procedure involving blood, and required blood and he took a transfusion. Only when something directly involves the GB or someone of that status the Borg may alter directives to protect their own behinds,
