Yield return

I saw this code and got a little confused:

 foreach (var entity in courses)
            yield return EntityToModel.CreateCourseFromEntity(entity);

 foreach (var entity in courses)
            yield return EntityToModel.CreateCourseFromEntity(entity);

 foreach (var entity in courses)
            yield return EntityToModel.CreateCourseFromEntity(entity);

 foreach (var entity in courses)
            yield return EntityToModel.CreateCourseFromEntity(entity);

What is the reasoning behind yield return in this case? Im thinking a normal return would break the foreach and that there are no need for using yield.

When googling i found that the yield can be useful to reduce code(look at attached image for example) but i cant see how it is contributing to that in the case mentined above.

Thanks in advance
