She looks to be opening up (forcing it vs letting it happen naturally) way too early, which results in her clearing her hips and not getting any brush interference.
I think most of the things going wrong are a result of not understanding brush interference and resistance. As others have stated she is trying to clear her hips and avoid contact and as a results opens early (get hips out of way), stay open (make sure there is no contact) lean over slightly (again to ensure hips and thigh are clear). I'll post a couple stills that will hopefully illustrate what we are talking about. Also a couple video links one is in Japanese but all you have to do is watch and you can see exactly what they are trying to teach (there are a few subtitles to help you along)
