It's not edge location count that matters, but Cloudfront doesn't use BGP Anycast but rather does a more traditional DNS-based routing and tries to spread the requests across multiple edge locations (even those farther away) for redundancy, intentionally.

When I asked for detail about why they don't use Anycast, the Cloudfront engineering team basically said their customers care more about uptime than latency and that full Anycast was too sketchy. Apparently amazon.com disagrees, at least. I'm also happy getting much lower first page view latency out of Cloudflare.
