Not quite. And opening an office in Reston doesn't a) qualify one as a contractor, or b) ensure that the Reston office will be the money making arm of the operation while its Googling cousins on K-street work the levers of power for the company.

A more likely reason why Google is opening up an outpost in Virginia: from a tax perspective, it's much cheaper to be there than in D.C. Which is why many contractors are located in that "string of office parks" as well.
