Could just be on the route from his ISP to the testing site. That I see all the time with those tests. I can sometimes get faster connections to JAPAN then I can get out some of the servers in Ohio, don't ask me why, but yea. Speedtest.net is known for having all kinds of constintly problems..its just the standard because its easy to use and pretty. It over simplifies, and even misrepresents, the truth most of the time though.
