Is that the shortest road path? He uses geodesic in his post. I thought it might be explained because of the projection used - projected distance measurements can differ from geocoordinate measurements. So I messed around in ArcGIS for a bit, getting WGS 1984 Web Mercator (auxilliary) projection length measurements first - that's the one used by Openstreetmaps, and I assume Google Maps uses the same. Then vanilla geocoordinate system. There wasn't a big difference between planar and geodesic. But I did find your proof that the line is longer: The other length measurement was 565 miles. Am I missing something or is he wrong?
