Does the Google Play app always updates automatically? I use Android 4.0.4 (Cyanogenmod) and I have the habit of disabling automatic updates for all my apps. I have noticed the Google Play app seems to update itself automatically -- when there are updates for any other app, I'm shown a notification mesage from the Google Play app, and I have to use it in order to update the app. But when there are updates for Google Play, it seems to autoupdate itself. Is it true? Is there a way to disable this?
According to the Section 3 of the Google Play Terms of Service you consent to Automatic Updates:


  Updates. You may need to install updates to Google Play or related Google software that we introduce from time to time to use Google Play and to access or download Products. Products originating from Google may communicate with Google servers from time to time to check for available updates to the Products and to the functionality of Google Play, such as bug fixes, patches, enhanced functions, missing plug-ins and new versions (collectively, "Updates"). By using the Google Play store and installing these Products, you agree to such automatically requested and received Updates.
