The AVO matters because the court tacked on a new condition a few months later in a hearing he wasn't even invited to: He was not to mention her publicly even indirectly (eg "one of the people running group X").

Identifying her in the video isn't resulting just in her seeking civil defamation against him but also pushing for criminal contempt of court (despite due process being ignored by the court).

Meanwhile she was allowed to continue defaming him. In fact him suing her for defamation is how it all started: she posted publicly that he is a sexual predator and stalker. So there are two opposing defamation cases in the pipeline and the one criminal case against my friend.

The successful AVO was intended by her to demonstrate to her thousands of followers that her accusations were valid, even though she had no relevant evidence for the rubber stamp AVO. The add-on was to gag him so that he could not deny the allegations she was publicly making against him.
