It is a well-known phenomenon that for a real binary signal, the best fitting binary has positive flux on one side and negative on another.
Here is AB Dor:
It looks bad because after optimization it is negative on one side and positive on the other. I think we should do this calculation in log flux so that it is strictly positive, but I wanted to check @shashankdholakia and @LouisDesdoigts agree.
