Safety. The general rule in Chemistry is to add strong acids to neuteral solutions first so that the exothermic result is small and controllable. But Bicarbonate is a week acid so it presents little danger and may need a little time to equilibrate. NaOH is a strong base and, depending on concentration, should be added slowly.
