Both incidents I have been informed of were on surface mix torches (one is quoted above and the other was a Delta). It is not as common as the internal mix, but it can happen. Be safe, use flashback arrestors.
Here is an explanation, long but informative:
While this is showing internally mixed torches, the principal is the same.

I like that they discuss gas properties and flashback. It goes along well with Raymond's link.
