Another point to consider is that you can't directly infer airflow from water patterns. The water has a lot more mass and will not be able to follow the same path/contours as air. I'm thinking specifically of what you were seeing at the leading edge of your bonnet for example, where the flow coming "up" from the grille is flinging water upwards, but the air itself is more than likely bending over the transition and staying attached on the bonnet surface, windshield and roof.
As for the pattern on the roof, consider things would also have been complicated by your wipers during the drive, no?
I think you're right about the rear hatch seeing separated flow though. While it looks like a gentle angle, my bet is that it's simply too steep an angle, and the flow separates fairly close to the top of the glass.
