normally span is when you want to make a small bit of text a different style and nowiki is to indicate to wiki not to use the code but instead show the actual symbol (like normally a colon with text after it would indent, but nowoki would mean it wouldn't indent and show the colon). However, it looks like on that page none of it was actually in use and was most likely leftovers from old code and someone forgot to remove the rest.
