As I see it, this merely means that your packs are comprised of matched cells, not via any intervention from the balance circuitry of the charger.
One would need to deliberately create an imbalance in a pack and then perform a storage charge / discharge to verify for sure.
Some chargers may balance throughout the charge cycle but most higher quality chargers do not do this as a default.
