From a longer title: This is a redirect from a title that is a complete, more complete or longer version of the topic's name. It leads to the title in accordance with the naming conventions for common names and can help writing and searches. However, do not replace these redirected links with a piped link unless the page is updated for another reason.
From a page move: This is a redirect from a page that has been moved (renamed) or is the result of a page move. One reason this page was kept as a redirect is to avoid breaking links, both internal and external, that may have been made to the old page name. Any redirect with a page move logged on its history page should be tagged with this rcat template.
