L was supposedly looking for places in the rotating reference frame where the attraction of the two bodies and the centripetal acceleration summed to zero. The amount of mass of a third body or its absence would not alter the solution, but enough mass would invalidate the assumption that the second body is in a stable, near circular orbit around the first.
