While bitflips are under a given threshold, the MTD core returns 0. However, when the number of corrected bitflips is above this same threshold, -EUCLEAN is returned to inform the upper layer that this block is slightly dying and soon the ECC engine will be overtaken so actions should be taken to move the data out of it. This particular condition should not be treated like an error and the test should continue.
