Narrative:

We were cleared position and hold runway 12. Moving into position, we heard tower tell air carrier Y to change landing runway to runway 9L. Air carrier Y replied unable. We then observed air carrier Y begin a go around from low altitude, less than 500 ft. Tower did not call go around. We were almost on centerline of runway 12 at this point just beginning alignment turn.
