Narrative:

Our aircraft was holding short of runway 17R, and there were no other aircraft in sight at the hold short area. Tower cleared aircraft (company call sign) to 'position and hold' on runway 17R. Looking around again, we saw there were no other aircraft at the departure area. Assuming that the controller misread our flight number, I read back 'aircraft X, position and hold, runway 17R.' there was no response from tower. As we began to cross the hold short line, we heard a voice on tower frequency ask tower to verify that the position and hold clearance was for aircraft Y. Tower replied, affirmative. We held our position, about 15 ft past the hold short line, and I advised tower that aircraft X had read back the position and hold clearance, and that we were about 15 ft past the hold short line. It was about this time that we saw aircraft Y turn the corner and approach the hold short area. Tower asked aircraft Y if he had enough room, and he replied yes and received a clearance to take off.
