When using microstepping the motor will be often in between magnetic fields, so disabling the drive will normally cause the motor to move to nearest magnetic field.
The maximum error in position will theoretically and practically be 0.9 degree on a 1.8 degree stepper motor.
Usually not an issue due to very often used reductions.
Usually on disable/enable and even then motor must be moved to error again, so it is not cumulative.
