That's a good example of something the article mentioned, which is that people from different disciplines (and, I'll add, people in different job roles) use the same terms differently. To a software developer, "requirement" has a special meaning. It describes how the software will behave. To most other people, "requirement" is just a regular word with its everyday meaning. It describes something that can't not happen. That something can be anything, not necessarily limited to software features. (They probably should be able to figure out from context what a software developer is really asking for, though. And one of these things is not like the others.)
