There was a follow-up, about a week after, where he keeps developing a mitigation strategy called "Hammer and Dance":

Coronavirus: The Hammer and the Dance

If you hammer the coronavirus, within a few weeks you've controlled it and you're in much better shape to address it. Now comes the longer-term effort to keep this virus contained until there's a vaccine.

This is probably the single biggest, most important mistake people make when thinking about this stage: they think it will keep them home for months. This is not the case at all. In fact, it is likely that our lives will go back to close to normal.

The "Dance" part of it is a modular set of social distancing measures that could be strengthened or loosened, whose goal is to keep the virus transmission rate under 1.
