Narrative:
Sfo tower cleared us to position and hold. I very clearly heard our flight number and the first officer read back the clearance. I taxied just past the hold short line then we heard tower clear another company flight to position and hold. I stopped and told the first officer to query tower. Tower replied yes we were cleared; but they didn't hear our read back; so they just cleared another aircraft for the same runway. Tower then canceled the clearance for the other aircraft and recleared us to position and hold.
