Anniversary Help - the letter X

In the Anniversary Manual it says "when X occurs at the end of or within words it is expressed by S slightly modified in slant". However I'm having a very hard time determining what exactly this modification in slant is... for example the outlines for "niece" (n-e-s) and "next" (n-e-x) look identical as far as I can tell. Am I missing something here?
