I think he's saying that inside of the loop in FizzBuzz, it should look like something like this (Python-esque pseudocode, assuming for a second print() doesn't add a newline automatically): if x % 3 == 0: print("Fizz") if x % 5 == 0: print("Buzz") if x % 3 != 0 and x % 5 != 0: print(x) print("\n") i.e. no special "FizzBuzz" case for when it's divisible by 15, it just naturally falls out of the first two if's. It's a bit of a silly objection though, the it's fine to write it as the author did.
