I guess they consider the taxable items to be discounted by the amount of the tax but that you're still actually paying the tax, rather than it truly being the case that the items are tax-free. I had a spend $30 get 3000 points offer recently, and I was careful to make sure I spent enough over the $30 to make up for any tax discount I would get, as I suspect the offer would not apply otherwise because of the strange way they apply the tax discount.
