What I got from the e-mail was that this is after the Obamacare website rework was already done, and they wanted the same guy to work on a "secret" Eric Schmidt project, since he proved to be a good leader.
Since the guy questioned "how legit it is", the insinuation I get from Wikileaks that this project was some kind of shady government spying project.
Edit: to be clear, based on the e-mail it could literally be anything. But I guess the main point is to show how tightly SV is integrated into the inner workings of government.
