Mission Control Help!

I was just watching a video from one of Apple conference demonstrating Mission Control. Whenever the guy went to it, all windows are grouped by app, but the thing I am having trouble with, and it is in the video but I don't know how to do it, or if it is there, is that the guy had 3 safari windows, then he did something to have them displayed as expose WITHIN mission control.

In the first picture, notice that he has Safari app windows (3) grouped on the middle, then, on the second picture he is still in mission control, but the has the 3 windows as expose.

Is it possible to do that? I have trouble selecting the window that is behind because there is no way to select it, because sometimes is blocked by the other windows. I have to go to app expose instead of mission control, but sometimes I actually need to have all my apps in expose and then select the window.

I hope I am being clear about what I am asking, because I don't speak english very well, but I would appreciate if you could please help me with this.

Thank you! It is with two fingers up. The only thing is that is still cover some windows that are behind. Hopefully Apple fix this. They just need to make it look like a regular expose (from Tiger and Leopard, that does not sort windows in a grid), because the way it is now, what is the point of having that option if you can't still see all the windows.

Unless is a screen size issue, because I am in a 13' MBP
