I think that's a feature, not a bug. You can stick the screw on the driver, and even though it's not magnetic, it'll stay on, allowing you to get into a tight space easily one-handed.

You don't really remove pocket hole screws much (though you certainly can with much less cam-out than Phillips head) so it's optimizing for the presumed one-way trip. I would assume anyway.

Almost every time I remove a pocket hole screw it's because I'm trimming something glued up (like a table top) and didn't plan for the saw blade when I put in the screws. Every time I think "heehaaw" and then I do it again the next time.
