Narrative:
Climbing out of phx on the snobl 2 SID; we received; 'climb via the snobl 2 departure except maintain fl 210.' we misinterpreted the climb via clearance and deleted the 9;000 feet hold-down at goaly. At 9;000 feet; the controller asked our altitude and directed a descent to 9;000 feet. The aircraft reached 9;700 feet before starting down. Prior to the hand off; the controller said there was no loss of separation between us and another carrier's flight in the area.
