Network connections are closed once the top-level VI finishes. Thus, when you run the "Open" VI by itself it is the top-level VI, and when it finishes, the connection is closed. When you run the "debug" VI it is the top-level VI, and the connection is not closed until that VI finishes, although you're closing the connection yourself, so that doesn't matter.
