Yeah, the nod isn't all too big, it's very subtle- also, Spartans communicate via a series of acknolwedgement flashes in their helmets- just before the nod (the nod happens almost right when he stops and comes out of the smoke), there is a series of flashes going on.
Like I said, it's subtle, and could be nothing- but it's fun to speculate :)
Like someone else said, too, the Spartans communicate through very subtle gestures- touching their faceplate where the mouth is means a smile, they spot a slight slump, or a twitch of the shoulders, suggesting a shrug- they know each other very well. (All of that is in the books by the way)
