Yup, correct. And interestingly the article says it was in fact blocked from view in some territories. Which makes me think that the copyright claim is not actually about the video content but likely audio. So perhaps they have blocked in territories where the video is not yet public domain and there’s a copyright claim in the territory (USA) where some other copyright controlled element is causing an issue.
