From what i understand, the named driver usually is put down as the registered keeper of the vehicle. So if anything happens and its the other way round, then im sure you will be in for a shock.
I was on my Dad''s insurance many moons ago, and he was the registered keeper and main driver on the insurance policy, I was an additional driver. To be honest, i didnt really drive the car much anyway as i was always at uni. I had a little bump in it once and they did pay out. So i guess its luck of the draw.
I personally wouldnt insure the car in your name if you are not the registered keeper though, i think thats cause for trouble
