In some Asian cultures (esp. Japanese culture), your blood type is suppose to be related to your personality, sort of like how your zodiac sign is suppose to reflect your "inner self". According to this cultural belief, AB individuals are suppose to be cool, rational and adaptable but they are also suppose to be overly critical and indecisive. AB individuals are also predisposed to have a "split personality" accoding to this theory. I don't know if that's what Ishida is going for but these characters do seem to have most of these characater traits.
