A puzzle to me is why the demons wanted to be in the swine in the first place, particularly since they just rushed off and drowned themselves after entering the swine. I could see a demon prefering life as a pig to being "deported" (see, e.g., Constantine) back to hell - maybe pigs have a rich life of sensation that compares favorably to being a demon in hell. But why go into a pig just to drown oneself?
