In fact, the lower voltage charger does keep adding amps, but they taper as the battery's voltage gets closer to the lower charger's voltage. Once the battery voltage is the same as the lower charger's voltage it does no more amps and the remaining chargers with higher voltages than the battery is at (and rising) keep adding amps.
Some smart chargers won't start if you start them in the wrong order, but that is a different topic? You start the lower voltage smart charger first and it gets going , then you start the higher voltage charger. Now they both run and add their amps.
