Yeah, it's a subtle distinction -- pure + and pure - habits decay back towards neutral (yellow) the less you do them, so you get more points for extra consistent efforts to improve habits and take more damage for continously practicing bad habits. On the other hand, the +/- habits hold the value indefinitely, for things that are good whenever you remember to do them or bad when you do them regardless of how long it's been.
