Your definition of persistent versus non-persistent is inaccurate.

A persistent XSS vulnerability is, well, persistent, meaning that you don't need to have the specialized query every time you want to display your content.

A non-persistent XSS vulnerability is just the opposite, where every time you want to display something, the query must be sent.

The picture you show for non-persistent is just a straight up not working vulnerability.
