All areas are affected with Machine Doubling that you posted. The devices are reduced. Not enlarged as hub doubling would make them appear. Look for the enlargement spread on the devices. Stop looking at the edges of the devices. Spread is seen on the centers of the devices.
Machine Doubling is caused after the strike with the machine damaging the devices. (reduction of devices) Hub doubling is on the die. So they term doubled die, means the deices are doubled on the die. (Enlarged devices))
