Narrative:

After landing, the tower told us to hold short of runway 35L. We both heard clear to cross. First officer responded clear to cross and the tower told us to hold short. We stopped the aircraft and were holding short of the hold short line when tower told us that she saw us moving and cleared us to cross. The aircraft that was holding for takeoff was never cleared and no avoidance maneuvers were necessary. Readback and confirmation worked well to stop a communication error.
