She's also wearing a different jacket at the end of the video. Continuity is not maintained when the video zooms back out to a wider shot after the close-up on her face. See, e.g., no zipper on end jacket and obvious zipper on jacket earlier in the video, or placement of the silver "buttons" and general structure of the lapels.
The background details are particularly "slippery" in these videos. E.g., in the initial video of walking along a snowy street in Japan, characters on the left just sort of merge into/out of existence. It's impressive locally, but the global structure and ability to paint in finer-grained details in a physically plausible way fails similarly to current image gen models, but more noticeably with the added temporal dimension.
