By the OP's reasoning, Star Wars consists of two trilogies. The protagonists of both series appear throughout the three films, but there are obviously crossovers.
To count SW as 'two trilogies' is of course slightly vague as it is clearly a franchise of six films, but given that the franchise consists of two sets of three films, filmed completely separately, does help. The notion of a trilogy has gained more power than it really deserves anyway: people often give trilogies more weight than to series consisting of 2, 4 or 5 movies, but this is pretty arbitrary. It probably exists because a) a trilogy mirrors the traditional three act structure, making the series seem more like a single entity, and because historically many great works have come as trilogies (Star Wars, the Lord of the Rings novels, the three colours trilogy, etc). It is also likely that is deemed a worthy yet realisable attainment of a series due to the law of diminishing returns. Until recently, most sequels were considered inferior, with very few exceptions (sequels are a lot more accepted these days of course). To repeat a winning formula would thus be seen as a great success. To do it a third time would be truly impressive. For a director to make a fourth succesful film would be asking too much. Thus the trilogy is deemed the highest attainable goal of a franchise. This is of course completely arbitrary and there is no reason why it need be the case, just look at franchises such as James Bond and Harry Potter (both of which, however, have the advantage of being adaptations of successful novels, but this is in itself no guarantee of success).
