The first circle is ~1.5" diameter and starts at Z0 and progresses around to 0.070" depth. The cutter continues its decent around the second pass, now at constant depth of cut of 0.070" and continues round and round until the final pass, cutting all the way through at 0.390". Then there is another cut again at the surface with a 0.125" larger radius, two passes to achieve a depth of only 0.120".
