"Google Play services are used to update Google apps and apps from Google Play.
This component provides essential features such as authentication with your Google services, synchronized contacts, access to all the latest privacy settings, and better and less powerful geo location services. .
Google Play services also enhance the experience of your apps. It speeds offline searches, provides more immersive maps and enhances gaming experiences.
Apps may not work if you uninstall Google Play services.

So I think that uninstalling these updates from Play Services cancels one of the mentioned changes. This is probably not a good thing to do if you like to update your apps properly via Google Play.
