That's the whole point. This is a younger Kirk than we see in TOS. He's fresh out of the academy, he's a hot-head, and he wants to show everyone he's in control. But he's not. Compare the scene of Kirk confronting Harrison with any of Shatner's Kirk confronting a similar foe. Pine's character is firey and shooting from the hip. Shatner's is cool, calm, and collective, and operating four steps ahead.
It shows the differences between the two characters both in age, as well as professional maturity. I think the best example of this is Pine's delivery of "I'm sorry" in the trailer. He realizes, finally, he's lost and fucked it up for everyone else (I think!).
