Because BJJ is, most likely, what she's facing-you don't beat BJJ people by rolling with kung fu practitioners, you do it by rolling with BJJ people and understanding how to beat their game with yours. Let's examine that more closely, shall we?

Of course, when you roll with guys almost all the time, have world-class skills, and they've been developed in Judo, where a fast ground game is the rule, not the exception, and have the right kind of coaching and strategizing, then of course you don't-as she said-need anything from BJJ, except to learn their strategies so you can develop counters to them, or traps for them......they are, though, apparently going to be the base/background of most of her opponents.
I mean, it's not as though they're going to teach her how to throw a person, or control them on the ground, or armbar them-is it?
Of course, it could be just as the Gracie's said in the video-she does have to overcome that "bottom=
losing" mentality from a lifetime of Judo.
Or it could just be to make videos like that one, so BJJ fanboys like
Xebecheh Hanzou can keep their worldview...
What makes you so sure she isn't?
(That's one of her striking coaches, Edmond Tarveydan....she really could be doing some gung fu!)
