I believe that they are for site administration and moderation, as Pet is a member of The Order (which us also a restricted coven) and it says that you have to be sent an invitation for those specific covens.

To put it bluntly, it doesn't really concern you either way. I don't think they would go as far as to hide the members of the coven, or else they just wouldn't have made it known in the first place. I think it just sets a title as well as a meeting place for mods etc. don't waste your energy thinking about it, it was made for them.
