Look at the centers of the devices for a doubled die. When you look at the outsides/insides of devices, you will find either Machine Doubling or die wear. On a doubled die, the doubling is on the die, not caused by the strike. Thus the reason they are called doubled dies, as the doubling is on the die. Machine Doubling can happen on a doubled die, but Machine Doubling can not create a doubled die. (Confused? Re-read the previous sentence that is underlined)
