I think that the point she's trying to make is that there's little variety in how women are represented in games since the target audience focused by game creators is not Everyone, but boys and men. Of course there are exceptions, and you can find more of them currently than in the past, but because games tend to be mostly oriented to men, they tend to use women scarcely.
When they do show up, it's generally in the roles of "goal to be achieved", "sexy bodies to look at/call attention to our game", side-kicks, walking jokes (Super Princess Peach comes to mind) or as women with "positive" (as in, "male") attributes.
Again, that's what I think her point is. And it's a good point to make, in my opinion.
