Not that it's only possible to when flipping, but it's more likely to happen.
Also, when staying upright, you are much less likely to land on your head WITH your body above you.... Hard to explain what I mean, but I hope it makes sense... If you stay upright and hit your head, it is usually a more horizontal fall with your head at a slightly lower level than your body.
If it makes you feel better, I knew what you meant. It's the reason why any jumps where the head goes below the body were illegal in the United States for so many years, even in training. They only made them legal because the Euro's were doing them. It's probably the reason all those off access jumps were developed....
Miss a 360, you have half a chance of not getting hurt since your feet still hit the ground first, and if your head does hit, at least you're not spinning head to toe. Miss an invert, and usually your head hits first, and even if it doesn't, you're spinning around the long axis of your body, and your head will hit hard with your body whipping. Paralysis and death are not uncommon results.
