I agree with machine/mechanical doubling. In the nanosecond after the die strikes the planchet, the die moves incrementally (usually seen as a slight rotation) as the die lifts off the planchet. It is not classified as a striking error; rather it is just post-strike. It is due to the die being loose in the chuck/holder ... once the screws are tightened, that type of doubling stops.
