I agree that in the context of a book about learning to code the construction given was a poor choice.
However, in terms of actual coding, that's a pretty common and also rather useful way to construct a loop. It makes it quite readable to another programmer and makes it much easier to follow the logical thread.
As for exiting in the middle of a loop being 'clunky' as someone else said, that's just total BS. Tying yourself up in coding knots just to avoid having a return out of a loop might get you a good grade in Programming 101 (or 301, even) but that's the only place that sort of crap will benefit you.
