Saying that Steve Jobs shipped frequently than Wozniak is like saying the manager of a software team ships more frequently than the programmers who wrote it, since he is the one who sends out the 'release notification email'.
Actually what he's referring to is that Woz basically made the Apple 1, made the Apple 2, and then, having produced two once-in-a-lifetime masterworks, essentially retired.
Jobs, though less technically useful on any one hands-on task, never retired even after getting rich. He just kept shipping, ultimately an order of magnitude more projects and a way more grandiose total portfolio.
Jobs vs. Wozniak? Jobs. Easily.
