Glass is not AR. Full stop. It's HUD for some definition of HUD. Your description is correct.

This is exactly right, it's not AR. What it has done though for AR is show people the idea of overlaying information on your environment which is a core tenet of AR.

That has been hugely helpful in making the understanding of how AR works accessible to a much wider range of people.

There are plenty of applications for mobile phones that do a much better job of that.

Examples: the Layar offering and automatic translation of text by moving the phone over the text and reading 'through' the phone.

True, I think worldlens is the best for that.

The AR mode of Flightradar24 is brilliant - hold your phone up and it overlays the details of a flight on the camera view.

I tried out google glass last fall and this matches my experience of it. It really doesn't overlay info as part of your normal view, which for me removes the AR designation. It does place information in a place that doesn't require you to move your head or look down, which is I guess where the "heads up" description comes in...but it still requires you to divert your attention, like looking at a rear-view mirror in a car. Sure, you can still see things in front of you in your peripheral vision, but that still seems less integrated than I would associate with the term HUD.
