missing feature of mission control?

i was watching this video where mac os x lion was being previwed.

i noticed when they were demoing mission control, they activated a feature that im sure is changed or not available anymore!

it looks about as handy as true expose.

does anyone know why they changed it to the worse version n the released lion?

what im referring to is the point at 14:40 onwards (14:49 to be exact)

with the lion im using, if i do 2 finger swipe up on the trackpad, i get a bit of zoom, but it does not make the surrounding apps become small and out of the way as much, and bring in as much zoom.
