This method of parking in a lower orbit is also why the trains of satellites are highly visible for a few weeks after launch. They extend their solar panels horizontally to minimize drag, which causes them to reflect the sun just after dusk and just before dawn. Once they reach their higher orbit they reorient their panels perpendicular to the earth, greatly lowering their apparent brightness.
