Why will there be two special points and not just one?
For instance, take a plane and some constant vector field, then fold the plane into a punctured sphere and extend the vector field to the whole sphere by 0 on the puncture. Why doesn't this construction work?

Good question. I can't see anything wrong with what you've said, so I'll see can I find where I read that there will be two "nodes".

You're right. I've removed the reference to the second point.
Sorry it took me so long to get around to this.

Oops, and the Front Page calls it 'Hairy Ball Theorum'. While it is a perfectly acceptable pun in French, I strongly suspect a typo here.
