This is contrasting evidence that she is worse when playing synergisticly with Xerath.
Moreover, when Kai'Sa plays with Xerath on the same side, she usually takes a little more damage than when she plays alone. Taking more damage may indicate that Xerath does a poor job of covering Kai'Sa during team fights.
