I only watched the start, but he describes the curve as having number of deaths as the Y axis - every description of "flattening the curve" that I have seen has number of cases as the Y axis. The point being to stop the number of cases overwhelming healthcare so that more people die - not just to rearrange when people who were going to die anyway actually die.

I don't know if that is a mistake or intentionally misleading - I would hope the former.
