ATCT local controller trainee clears an air carrier onto the runway for departure without recognizing a twin cessna on half mi final. As air carrier begins to taxi, tower local controller instructor issues clearance for twin cessna to go around. Air carrier stops at runway to see twin cessna cross overhead and in front of aircraft.

Narrative:
Holding short of runway 19R at sna, tower (first voice) cleared air carrier #1 into position and hold runway 19R, which I read back. Another (second voice) tower transmission directed a twin cessna (aircraft #2) on final (approximately 1/2 mi) to 'go around.' I glanced up and observed the cessna (aircraft #2) initiate the go around while captain brought the aircraft to a stop, after having moved approximately 10 ft short of runway. After approximately 30 seconds, original tower controller again cleared into position and hold runway 19R. Everything was normal from that point on.
