Narrative:

While on a scheduled passenger flight from phx to ont, we avoided what could have been a runway incursion. Cleared to land on runway 26R, and on a 1-2 mi final, I heard the tower controller tell an aircraft Y to 'position and hold runway 26R.' thinking the aircraft Y pilot could see us on short final, he would not accept the clearance and/or wait until we touched down, I said to my captain, 'if he moves, I'll say something.' I saw his propellers pitch forward, and he started to creep forward, so I transmitted on tower frequency 'you may want to wait until we land.' the aircraft Y pilot responded immediately by stopping, what looked to be short of the runway. A normal landing/rollout was accomplished and apology made by controller.
