Probably cause the people doing the check are so faulty in the first place. Somewhat like how they miss a passenger, or have a stowaway on board. And somehow airlines never catch it.
Even with their double-check they probably make some mistakes as well (I know NZ flew people to transit through Taipei when they couldn't actually do that, and the passengers got stuck there).
