I hate doing microscopic analyses, but oh well..
Anna doesn't have a perfect lutz technique, but her edge seems outside to me.
Moreover, it seems outside enough to escape being called a let alone flat-edge, and obviously a flutz

For people judging lutzes, it's important to see the edge at the moment second foot hits the ice, picks in, (not the moment skater leaves the ice!)
True flutzers have an inside edge the moment the second foot picks in. So I disagree with your assessment of Anna's lutz.
Do you have a source for this? Genuinely wondering if this is how it's written in 'Le Ole Rulebook'
