Any kind of edit changes the page source. By using VisualEditor users have a medium between them and page source, and because VisualEditor has many bugs (some of which are fixed in later versions of MediaWiki that Wikia won't update to) that medium isn't perfect and usually inserts unnecessary wikitext into the page. For example, you might stumble upon VisualEditor edits that add text or something similar, but the source can be simplified to just text instead. That's how VisualEditor can make the page source less readable
