Take for instance this video in the UK, from 1:14 onward. She sure is good and what she does works really well for what she's doing, incorporating it into a break dancing routine, most impressive for that purpose, but I would not do what she does in the video if I was in a real fight.
She's also a world kick boxing champion so she can adapt her style to what is needed so don't assume that because she can do the handy bendy stuff as well as her stunt fighting she can't actually fight, she can, very well in fact.
