Thanks for the info; that explains what's happening better than the settings descriptions do. I was aware that the Note prioritized a "near touch" by the stylus before rejecting any touch input, but had gotten the impression (from Autodesk's dialogs) that turning on "Pen Mode" ignored touches completely.

I've also added the link to your site, which I'd neglected to include earlier, and fixed the capitalization. For me, Sketchbook simply has the advantage of several years' worth of familiarity.
