Now I don't have physical data to back up that claim so maybe they know some special case where that may help, but from a science standpoint it makes a lot more sense to have one solid piece of copper for the best possible heat exchange. The only thing I could see changing that is if TIM conducts heat better than copper. Given that too much TIM makes it act like an insulator would make me think otherwise.
