@parpk, @jeriksson:
It seems that you confused a bit the Share button and Like/+1 buttons.
Please check out this article to know what’s the difference between Facebook Share and Like buttons and how they work:

Also please check out this discussion to understand better why you don’t see your likes on your timeline:

Briefly:
The Like button also shares an URL of the liked page but usually not on the timeline, in other places which are available for your friends.
Also if you have a company page on Facebook and you set an URL of this page to like in the locker options, users will get subscribed for updates on that page.
The Google +1 button is designed to give your recommendations for the page you have +1ed.
It means that this page will have the better ranking in the search results. Your friends will see your ‘pluses’ in the results when searching.
The plugin uses the standard social buttons created with the respective social networks.
You can learn about benefits of each button without regard to the Social Locker. In the Social Locker, they work the same way.
By the way, the premium version of the Social Locker contains the Facebook Share button if you need it.
Please let me know if you have other questions. I will be glad to answer to them.
