Because once the boolean is set to false, that's all this method can ever return. I found this potential issue using a case tools audit feature.

Actually, the way the loop above is written it already will exit
immediately when found_it is false, as part of the "i > -1 && found_it"
clause in the for loop, so adding break statements wouldn't really gain
much except possibly avoiding the second if statement...
