That's what a redirect is, reading the value of the location header and then requesting it. How do you not follow the redirect by reading the location header? Once you've made the request to the /goto url, with GET or HEAD, to get the location header, google knows you're interested in whatever it is putting in the location header and can assume you're going to go there, if you're letting the User Agent (curl or the browser) go there for you or not.
