The difference is that "do not track" isn't enforced at all.
It would be much better to make a browser-side dialog like it's done with location tracking and desktop notifications, and also provide a checkbox in the settings. Most importantly it would take away control from shady websites to implement it on their shady terms(though admittedly giving that control to Google's browser may not be ideal either).
