Nope. The Location On setting is referring to the ability of 3rd party applications (e.g. a navigation/mapping app) to get access to the GPS function on the phone. The carrier can always ping your phone to determine where you are. It's generally used for E911/emergency uses but there's nothing in the protocol (that I'm aware of) that enforces any kind of check to see that you, you know, placed an emergency call. Even if you didn't have GPS in your phone (say it was an older phone) the carriers know roughly where you are at any given time just based on the cell tower that you're connected to. Of course that assumes you leave your phone on, which some people of course don't, but the VAST majority of people do, which is why this is an important initial ruling.
