It was a fun time watching this one over and over. I also figured out that your anchor point has to be set at the center and you have to animate the path position. After attempting to animation the transform position first I couldn't figure out why the repeater wouldn't work until I did this. Happy to hear if you can do this, and I was just doing it incorrectly.
Also learned if you set photoshop to forever looping and then change the size it reverts back to once. The little things you learn by practicing.
