I just did a quick look through the doc but it does not appear that they take into account that Dyson shell elements would try to radiate waste heat directionally to the north and south of their orbits as to avoid too much thrust from radiation that may alter their orbital paths or the paths of other Dyson shell elements. The signal this would create to an outside observer I think would significantly change the heat signature and periodic changes, depending on our observation angle to the star.
