Liveaquaria got their banana/sunset wrasses messed up. Yellow has nothing to do with being male or female--actually, being yellow can be either. The only thing it means is that that particular fish is still in the initial phase. In the initial phase, there is no reasonable way to tell the sexual differences between individuals. In general, Liveaquaria does a very good job and is usually correct, but they market things incorrectly sometimes (not purposely), so you must be cautious on what you buy. That being said, I also highly disagree with some of their species profiles, as well. Some are either plain wrong or misleading.
