It is possible, but that is just how our own moon formed; their moon could have formed completely different or maybe it still isn't fully formed at all. As we have seen, their moon has various phases, with the moon itself seemingly become more or less broken apart. This could be because the back half of the moon is broken or maybe there is some odd gravitational anomaly where the moon will occasionally drift farther away from the planet, causing gravity to become less and the moon to break apart before reentering a closer orbit and becoming whole again. Or it could be the other way around, with the moon coming closer and the planets gravity drawing the smaller chunks of moon out, but the moon's own gravity prevents them from crashing into the planet.
