DRV8711: 1/256 microstep and stepper motor accuracy

Part Number: DRV8711

for most 2 phase hybird stepper motor, the step angle is 1.8 degree, and normally motor accuracy is 3% or5% of step angle, so is about 0.054 degree to 0.09 degree, 

but for 1/256 micorstep drive, on step is 1.8/256=0.007 degree, which is much smaller motor accuracy , so can not achieved by the step motor, so what the meaning of the 1/256 microstep?

thanks.
