I don't think it came off that way at all. He's stating that he can demonstrate a basic, fundamental grasp of code structure in several languages and types of languages, which is pretty good.
I don't know, maybe it's just me, but I think the only thing easier than FizzBuzz is Hello World. I wouldn't advise anyone to mention they can write one in their resume.
I don't have any reason to believe he put it on his resume.
As for complexity, FizzBuzz is nothing like Hello World. Hello World only shows that one knows how to make a program compile/interpret and display fixed output. FizzBuzz demonstrates the above, plus an understanding of looping, basic arithmetic operations, and how to create program flow from that. Like it or not, that covers most of the actual coding requirements of probably 90% of jobs out there. It shouldn't be a deciding factor in getting hired, but it's an excellent first step in weeding out those who shouldn't be considered.
