Every google search result you see is masked to have a boat load of tracking that identifies you, your search query and a variety of other details. When you click out from Google you are first bouncing through Google's instant redirect before you are taken to the target website.
When users click the back button they bounce back through the redirect to the SERP.
You can test the tracking by right clicking and copy/pasting the URL of any Google search result. This can be stripped using add-ons (and I highly recommend it).
