Narrative:

At cle, was asked by ground control to follow aircraft ahead and monitor tower. We switched to tower, they then advised aircraft ahead to 'taxi across runway 23L, into position and hold runway 23R.' I believe the captain was still thinking he was to follow that aircraft. So, as he proceeded across the hold short line for runway 23L, I mentioned that 'I think you're supposed to stop behind the hold light bar.' at that same moment the tower sent an aircraft around and advised us we were on an active runway. I estimate 10 ft across the line when he stopped.
