I do understand how it works and can confirm that AWS does not use it for the IPs served for the subdomain-style S3 hostnames.
Their DNS nameservers which resolve those subdomains do of course.
S3 isn't designed to be super low latency. It doesn't need to be the closest distance to client - all that would do is cost AWS more to handle the traffic. (Since the actual content only lives in specific regions.)
