Hey tempy, This ID value is unique to the Google App Engine Users service, and won't be the same as your general Google account ID. You can view the difference between the two ID values by playing around with http://gae-login-explainer.appspot.com/, which also explains the main differences between the Google sign-in for websites button and App Engine login URL methods of authentication.
Let me know if you've got any questions, and I'll do my best to help clarify.
