I would guess that the author copied the results into a table and prettified them and added in details like location. At the top of the screenshot it says "traceroute from London to ..." - no traceroute program knows where it is in the world! Also the locations of each hop in traceroute NY > Chicago > Ashburn etc., no traceroute program will know where in the world those IPs are. I suspect the author has guestimated based on the reverse DNS record for the IPs and latency. Traceroute does have the ability to show you the ASNs in a path but that is based on a WHOIS lookup of the IPs that it's discovering. So it could be wrong by assuming the IP address of each hop was announce by the ASN that owns it.
