And the adjacent graphs show phase (line growing longer, spreading along an orbit), and plane (line breaking into multiple lines slotting into nearby orbits). Positioning is accomplished by spending time at different-than-deployed altitudes, mostly lower. Lower gives a difference in nodal precession (Earth being non-spherical), IIRC something vaguely like half a degree/day difference out of several deg/day, slowly changing plane westward. Thus plane changes take weeks of drifting. Launch being far more about "go fast (in some direction)" than "while being high", rapid plane change (direction change) would have prohibitive "launch-like" energy cost. So a single launch will populate one or few nearby planes. And finally lower orbits orbit faster, quickly overtaking deployed sats in a single plane to reach deployment positions. Kerbal Space Program is thought a fun way to play with such.
