Reading through the support page, the way it works is that once every 12 months, Google will allow you to "change" the email address associated with your Google account. In actuality, the process is more like adding a new alias email to your account since your old email address will not be deleted and will remain functional. You still get one email inbox and outbox, but presumably, you will be able to do some filtering based on which email a message was sent to, as well as choose which email to use for outgoing messages. Essentially, Google is giving users a way to associate up to three new email addresses with an existing account and all of its existing data and services.
