The points jersey is decided on total points. For the sprint finishes, winner gets 35 points, and the number of points decreases down to about 25th place. However, most stages also have "intermediate" sprint lines at several places along the course. To get the green jersey, you need to "chase" as many of those intermediate points as possible, too. In the end, whomever has the most points wins the jersey. You DO get the biggest points for winning a stage, but even 4 stage wins wasn't enough.
