Narrative:

Told to hold short runway 25L. We were at intersection P and started to cross runway 25R. Tower controller asked if we were holding short of runway 25R. We said negative, we were told to hold short of runway 25L. After crossing runway 25R, noticed commuter aircraft take off on runway 25R. Estimate he was airborne 6000-7000 ft prior to intersection P. I believe tower mistakenly told us to hold short of runway 25L, when he meant runway 25R. At all times we monitored operations on runway 25R and could see an light transport holding for takeoff on that runway. Apparently he was given takeoff clearance just as we started to cross runway 25R!
