Shirley, it's not a matter of terminology. AA does not have people who lead or people who consel, no matter what you call them. The meeting secretary does nothing more than get the meeting started on time, introduce the chairman and handle a few announcements. Most groups rotate the position every three months. The chairman is a different person every week, just a speaker who talks about their own experience for ten minutes or so to get the meeting going, and then calls on members of the group to share their own thoughts.
The group itself is run by the consensus of its members. Every group is autonomous and free to run its own affairs within very broad guidelines. Which is why I tell people not to judge AA by one group. If you don't like one, go to another one; they can be very different. There are also meetings just for men or women, and specifically LGBT friendly meetings. Many of us have problems unique to some background of our own.
Was your friends husband a licensed counselor? He might have been leading a support group seperate from AA. Or he could have been a sponsor, although that only involves helping one person who has asked for his help in gaining sobriety. A sponsor only has no authority, he can only make suggestions, and the sponsee is free to pick somebody else anytime he wants. I had three my first year of sobriety and we're all still good friends. It's also possible that he was meeting with several sponcees at once (not usually pracitce, but done sometimes just to get everybody together). If so that was not an AA meeting.
