If you want to be really really confused, read what the stewards said about it.

"We applied the Driving Standards Guidelines as a guide to determine who had the right to the corner. Applying those guidelines, it is clear that LAW was well ahead of DOO at the apex of the corner and was entitled to use the full track at the exit.

DOO should therefore have given LAW sufficient room to overtake and his failure to do so resulted in a minor collision. As the resulting collision was minor, we took no further action."
