I've never found any legit info on why this happens either but it has been observed to happen only on next attack modifying abilities such as Rune strike/Heroic Strike and on yellow specials. Enemies without a shield can also block your crit for whatever reason. If you want to read more there's about as much info on wowwiki.

Expertise and hit have nothing to do with it.
