Coolness by association.
Notice the bottoms of both logos. The logo on top elicits feelings of pride in virtually every American. Microsoft Word is a robust product that runs on many platforms, leverages the intelligence of the user and, frankly, makes them more productive. It is the logo of a homegrown product that authoritatively projects the reality of American greatness around in the world.
One wonders if the waves on the bottom of the second icon are an attempt to piggyback on those deep feelings of pride and cutting edge coolness.
