Narrative:

After landing runway 25L and clearing runway on taxiway J, held short runway 25R. Tower then said to hold short and we read back. While holding for crossing clearance, the first officer went to ramp frequency while I monitored tower. Tower then cleared air carrier X to cross runway 25R. I read back 'air carrier X cleared to cross runway 25R.' as we began to cross, tower had us hold and told us the clearance was for air carrier Y to cross. Our nose was over the hold line, so tower cleared us across runway 25R. The first officer had come back on frequency as I read back and cleared the runway before we began crossing. In hindsight, I would have had the first officer stay on frequency with me, to back up clrncs.
