He's talking about the part where Snake and Meryl are
in the room where you fight Psycho Mantis, and they are both standing in front of the desk and shooting. Meryl has a Desert Eagle, and I think Snake has the FAMAS. The part where Snake and Meryl actually shoot at anyone together is just after the DARPA Chief dies (not the Chief.. the other dude.. the member of FoxHound..) in the cell, and you are shooting at guards from inside the cell block hallway.
There are other parts in the original trailer that did not appear in the final game, such as Snake placing around 30 or so C-4 explosives around the second game area (where the first truck is), and detonating them all one after the other, killing about 10 or so guys.
