If it was intentional then Ben had some reason for wanting to get inside the Swan station. When they have the lock down and Locke gets stuck under the blast door Ben has to go push the button. You would have to say he did push the button, because the place didn't implode. So he lied to John saying he didn't push it. What else might he have done when he was alone in the computer room? Maybe this would be a reason to intentionally get captured.
