It's only spg points purchased through points.com with the spg card. Not just points.com in general unfortunately. But still nice if you're going to do it.
Here's direct from the FAQ on buying starpoints:
"Which credit cards may I use to purchase Starpoints?
You may use any valid American Express, Visa, MasterCard, Discover, JCB or Diners Club card. If you use the Starwood Preferred Guest Credit Card from American Express to purchase Starpoints, you will earn additional Starpoints for the dollars you charge on the card."
