That's really cool but it's wrong due to testing bias.

I guarantee NYC and the West coast both had cases growing nearly simultaneously.

I am not smart enough in biology to refute this, but it looks like they've been tracking mutations / genome, so maybe they can tell what order it showed up in places?

NYC likely got hit with two versions.. one from Asia, via the West Coast, and then later through Europe.
