Yeah, the very next line below the pasted screenshot says: "Please note that Self-Driving functionality is dependent upon extensive software validation and regulatory approval, which may vary widely by jurisdiction. It is not possible to know exactly when each element of the functionality described above will be available, as this is highly dependent on local regulatory approval."
So, basically you are buying the promise that some day in the future is will work. It sucks that they are charging people who are leasing the car for this, as there is a very real chance that it will never work during the term of their shortest (2 year) leases. (if ever.) There were things that the V1 autopilot was touted to be able to do that never panned out (and I still maintain never will.)
