I would say that is generally true. Sometimes you have a female in a smaller enclosure with too many distractions, the substrate isn't deep enough, or she's just inexperienced, and the eggs might be fertile even if they are laid on the surface. One of my females dug a quasi-hole, laid eggs and didn't cover them up her first time. They ended up being fertile (well one of the eggs was anyway). After the first time, she's buried her eggs ever since.
