Narrative:
Captain may have taxied over the hold short line prior to takeoff clearance for runways 9L and 12. It is difficult to tell if the hold short line is for both runways or if another line exists closer to the runway. I would recommend that this area be marked in such a way as to eliminate any confusion.
