Nah. The writer thought he could get away with doing something cute.
I actually like most of ST:ID, but that particular scene made me laugh the first time, and pretty much just irritated me after that. The movie would be better if it were edited out.
If I have one complaint about nuTrek, it's that it tends to lean a little too much to the slapstick side at times. Beyond that... I'll watch 'em, and that says enough.
I actually really loved Spock' yelling out Khan. First and foremost remember when vulcan's lose their cool, they really lose their cool, and this Spock and this Kirk are close, certainly closer then at this stage in the Prime Universe (which is before they would have served together), and add to this Spock having been exposed to lose on a scale that prime Universe Spock wouldn't experience in his own universe. That and dialogue and events that occur differently and at a much later date in the Prime Universe also play into two well regarded Next generation episodes, Cause and Effect and Parallels, where we can see how changes in time can have similar events occur at different times, and by different people.
As for JJ Trek being campy at times, that absolutely goes back to TOS, which used humor far, far more often then later series, or even in many cases more then the original TOS films (Voyage Home of course would be a big exception). Heck I just rewatched Ultimate Computer last night, and after the enterprise under the control of the M5 completely kills all life on a constitution class ship and dozens on the other three, what happens the episode ends with Kirk, Spock and McCoy sharing a little humor. This wasn't an example of rare behavior this was an example of the typical manner of how the show ended, let alone the humor that could be in the middle of an episode, even quite serious episodes. It was extremely rare for the show not to end, completely and inappropriately with humor, when the story absolutely shouldn't.
In fact in my opinion, JJ films have often been closer in spirit to how Trek was presented (just with state of the art methods of today) then most of the Trek that came after the Turnabout Intruder. Of the original TOS films the one that I felt most closely feels like TOS is the Undiscovered Country. That isn't my favorite TOS film, but it certainly felt in all aspects to be the film most like TOS, followed of course in my opinion Trek 2009, into Darkness, Voyage Home, Search for Spock, Final Frontier, wrath of Khan and finally the Motion Picture. Of course my ranking of how I judge the quality of the final product as film is Wrath of Khan, Star Trek 2009, Into Darkness, Undiscovered Country, Search for Spock, Motion Picture (this movie and the it's style is much better suited if it was made for TNG then for TOS, and last in every way in my book the Final Frontier. Of course in my opinion, you want to watch quality Star Trek, you don't watch a movie to do that (overall I am not the biggest fan of Trek on film. I think each of the live tv series have all produced several episodes that i would rank better then the movie I like best.
An example of another TOS fan, a nearly original one (I have home film of me as a very young child totally enthralled by it, but my actually real memories off Trek aren't until it was put into national syndication in the early 70's), that loved TOS through to JJ Trek (warts and all, and that applies to all versions, TOS, Animated, TNG, DS9, VOY, ENT and reboot universe). And the attitude that AP and Crew are the carriers of "real" Trek more then anything make's me want to see their efforts turn to folly and ruin.
All I will say is that I don't mind humor; nuTrek just tends to go a bit more over the top than it should IMO. I don't compare it to TOS; I evaluate it for what it is.
