  The equation to determine watts is P=VA

  If you have the same voltage and a higher amperage, then by definition you have a higher wattage.

    Dammit, thought they all multiplied into a fourth thing.

  Wattage = V x A.

  They’re pointing out that it’s impossible to hold both wattage and voltage constant while changing the amperage.
