That will give slightly preformated content, so list of links to referencing tiddlers, preceded by the header "The following tiddlers contain fields, links, macros, transclusions, or widgets referencing this one:"
<$list filter="[relink:references<currentTiddler>!title[$:/StoryList]sort[title]]"/> was just to demonstrate that the real value is in the filter [relink:references<currentTiddler>!title[$:/StoryList]sort[title]]. As is, that list widget example does the same thing as the transclusion minus the header, and that's not so much of a big deal.
It's just that using a list widget provides way more flexibility than the transclusion. The list can be formatted however anybody could want, having a modal per tiddler instead of a link per tiddler, or maybe setup the list of tiddlers in a table instead of a list, or whatever other custom layout/formatting.
