yes. i know what an unsubsidized iphone is, and i know what factory unlocked is. What I dont think you are understanding is that officially according to Apple spokesmen and media...the iphone 4S is not officially available unlocked yet in the USA until mid November. That being said, as the article you linked to states, select stores (which as it seems random) are offering the unlocked device earlier than the official date.
If you can find me an official statement from Apple that gives a list of stores offering the unlocked iphone before middle of Novemeber, then I will take back the "random" statement. Until then, accept your defeat.
