I think that's right. If Mayak is as depicted in http://space.skyrocket.de/doc_sdat/mayak.htm , then it will only be extraordinarily bright when one of the faces of the tetrahedron happens to be oriented to reflect the sun at the observer -- or, I suppose, a bright part of the Earth, like sunlit clouds. Otherwise the faces would be reflecting black space and you'd just see the small main body and perhaps not even that if it happened to be behind or shaded by the tetrahedron. Getting light curves would be of interest.
