Article mentions that this is just the high-altitude constellation in MEO, and there will be as many as 12000 total at all altitudes. Putting 4425 in MEO, another ~7500 in LEO, and maybe a few in higher orbits, is likely a plan to reduce latency and increase bandwidth. SpaceX has already launched some (50?) IridiumNEXT satellites, a planned constellation of 66 operational in LEO, plus 9 spares in a lower orbit, and 6 spares on the ground.
