It's the same thing, just applied to a different kind of fish. I don't know enough about betta "sororities" to comment on its effectiveness. However, I know enough about bettas to say that they are not territorial in the same way as African cichlids, so I would think its likely to not work the same way. With Africans, because of the way that territories are carved up in the tank and because of the number of threats to each's territory, it is sufficient for them to simply drive the other fish out. Because bettas don't have such well defined territories, I think one is more likely to follow another around, an there is MUCH more fin to be nipped. Some people think that their fishs fins have to be perfect, however, when keeping more aggressive fish, this is not always attainable. I know in my experience as a professional fisherman, it's very common to see less than perfect fins. With regular fish, it's not really that big a deal, aesthetically speaking. However, bettas have beautiful fins that don't look good when they are damaged, and they don't heal as well as regular fish. Personally, I keep fish in part to admire their beauty, and since a significant portion of a bettas beuaty is tied up in its fins, I would be very hesitant to subject them to conditions that might result in them having anything but beautiful fins. But that's just me.
