If your engine gets stuck with wide-open throttle, the kill switch may not kill the engine, so don't rely on it in an emergency situation. Do use it by all means but also apply the brakes and compression release if applicable. You can also try to pull the plug wire if possible but you may get a good shock in the process so don't panic.
Just some helpful hints to keep from getting hurt in a panic situation.
Good points, I hope that you are OK and didn't get hurt when your throttle got stuck.
