Cause they wouldn't open everything up at once and people have shifted their behavior for the foreseeable future. I imagine a series of flattened curves one after another through the end of the year will be what happens as they open up pieces of the economy, presumably with better testing and tracing to control outbreaks (still to be seen).

Bay area new case count is pretty much flat at this point, and I don't see why it would be that much lower in June, the thing is bubbling under the surface and won't go away until a vaccine.
