Quite often they put two terminals on the alternator and then run two cables from the big terminals back to the same connection on the starter motor terminal which is then connected to the battery. This was to simply split the load over two cables so you din't need one big cable going to the alternator, two smaller cables could be used instead.
You can run two separate cables or connect the 2 terminals together with a short link cable if the single cable you have back to the starter is up to the job of carrying the full current.
