This sounds clearly like the official is "counting the basket" by indicating how many points are scored. This mechanic was eliminated a year before I started officiating and I remember guys using this the first year I worked basketball. It is not a conference thing, it is just something officials that have been around a long time have been doing and did not ever change. It really is not a big deal; I can just tell who has been working games longer than I have when I see the signal.
