Objects at Lagrange points L1 (between), L2 (small-body side), and L3 (large-body side), either have to continually spend propellant to keep station or use a Lissajous halo orbit around the point. In space, the choice to use more fuel or less fuel requires little consideration. So this satellite essentially scribes an elliptical ring around the sun as viewed from Earth. If the Moon passed between the satellite and the Earth, the Moon would appear from Earth to be 4-15 degrees away from the Sun, which would just be an ordinary new moon, not an eclipsing new moon.
