You are correct about the construction being different, but as usual incorrect on the reason. The ef-s, short back lenses, allow lenses that are lighter, due to the reduced image circle and distance to the sensor.

Even though ef-s lenses don't have a red ring, the 10-22 and17-55 are considered the equivalent of l glass.

I don't know about the red ring thing. But is the reason purely mechanical - like the mirror hitting the back of the APS lenses or not? No one has given me an exact answer so I suppose Canon is clouding the issue and everyone is afraid to try it out as they don't want their mirror to break..
