If you go on the page now (and it's been that way for a while), the only extra features that FSD promises over the original EAP options is Traffic Light and Stop Sign Control and Autosteer on city streets (coming later). They no longer advertise like you say (like punching in an address and car driving itself).

I believe originally the promises were more on that order page, but not anymore. Trying to find an internet archive link that works to show the previous wording, but haven't found it yet.
Edit, this is the best picture I could find, which Teslarati had of the previous wording back in 2016:
