Just because he didn't move pixels across the screen doesn't mean he wasn't setting the design language, defining taste, sweating detail and holding the vision. No-one would suggest that a show-runner didn't make TV, or that a director wasn't a filmmaker. Jony Ive's design changed (and improved) immensely one he was working closely with Jobs. Once Jobs was gone things drifted. Similarly Pixar was hyper-focused under Jobs then began to drift as soon as he was no longer involved.
