Then they either stay red until the controller hits the other button or, if you trust the automation, it could automatically turn off the red lights as the departing aircraft passes. It still doesn't account for someone running a red light but it might at least cause a pilot to query ATC if given an instruction to cross when the light is red.
To all intents and purposes, that's what IAD already has (apart from the redundant green takeoff light). See post #20.
