Indeed, and it's a bit of an anomaly because of that. I'm giving the AS a trial right now. Most of the safety bar razors are oriented toward the steeper angles, but the AS's shaveable range is more shallow (and very narrow because of so little blade exposure). It's a lot like an open comb in geometry, but with a safety bar.
This is close to the method I use with the AS-D1. I feel mostly smooth clap with a touch of blade. My variation is turning the head so that it slices more like a slant. You can make as many passes as you want with zero irritation.
