Narrative:
Air carrier X was asked to amend his assigned altitude, to ensure altitude separation between air carrier X and air carrier Y. A GA aircraft, air carrier Z, read back air carrier X's amended altitude and air carrier X continued descent through air carrier Y's altitude. Hearback readback.
