It's because each percentage gets added to each other, so you don't get various multiplications by 1.2, but only one percentage with the total, and therefore only one multiplication.

So instead of DEF 142971 with five Super Attacks you get DEF 114914, the multiplication by 2 being equal to a boost of +100%.
