I got the feeling that they were intentionally trying to push the point that their employees had families to try to counter the stereotype of the 20s, childless workaholic that many have about Google. But part of its feeling staged is likely due to the fact that the presenters are real Google employees who's skills as actors are pretty limited. If you had professional actors presenting, it might feel more authentic despite actually being less authentic.
