umm i believe he is just basing it on the single player ultima's not UO and Order and Chaos were more to do with Serpent Isle (though did affect Britannia).Alot of the factions from UO are just taken from them such as the Shadowlords(Ultima 5), Order and Chaos(Ultima 7 part 2) the other faction your thinking of is Minax(Ultima 2) I think.
