Probably more amusement than sarcasm (but no offence taken!). I just thought this is a really funny page from Google. Although this is a very clear joke from Google, this doesn't necessarily mean they are not working on something serious with these kind of gestures.
Also if you are watching the accompanying videos and this wife: 'we are made for kill' - really very funny!
