It is because as a member of the punting team, being the first to touch the ball is actually a penalty. The penalty carries no yardage with it, but the receiving team can choose to take the ball where it was first illegally touched, or they can choose the result of the play as it is carried through.
If you watch carefully, you will notice that if a punt team member touches the ball and leaves it laying there, Golden Tate will make a charge at the ball. This is because he could pick it up and run with it, and even in the worst case of a fumble, the Seahawks could take the ball where it was first illegally touched.
Yes, this is the rule, pretty much straight out of any rule book (HS, college, pro). If the punting team touches the ball, the return team essentially has a free attempt at a return. In the 80's & 90's when the punting team would surround a rolling punt, it was not uncommon to see the return team attempt to push one of the surrounding guys into the ball trying to get them to touch the ball, then try and advance the ball.
I saw it first hand, my team punted, and one of our guys downed the rolling punt by picking the ball up and immediately dropping it. The return team then pick the ball up, returned it, fumbled, my team recovered. The return team got to keep the ball due to our first touching the ball.
That is why when the punting team downs the ball, they hold onto it until the refs blow the whistle or they give the ball to the refs.
