The difference between the two patterns are the type of enemy (5-rarity has 1 more yari) and type of troops they come with (as you can see above). There are probably differences in the enemies' stats too but we don't know for sure. Their appearance is probably not decided by any sword factors since I've had both patterns appear with the same group of swords in my team, but 5-rarity tends to appear way more often, so you're not getting anything unusual.
