Couatl_Updater2 isn't tied to just GSX, but rather all FSDreamteam products. As I said in my previous post, Couatl_Updater checks to see if Couatl_Updater2 is up to date, and if it needs to be updated, it'll get updated. Once that's done, it runs the update itself. If you run Couatl_Updater2 directly, it'll run, but it might not be up to date.
