... You're correct in that the charger does not balance cells, but the BMS balances if needed when at the float voltage and charge current is small. If you shut the charger off early rather than lower the float voltage, current remains high and balancing does not take place.
Did you find that graph somewhere, or is it from your own set of measurements?
