Not completely true. I have done the exact same thing (more than once), and the unknowledgeable agent let me order the pack. The miles posted, my credit card was charged and after about 3 weeks the miles were deducted, and the money redeposited to my credit card. Might come handy when ordering an award. And yes, it is possible to have a negative account balance.
