If you only include specific helper modules, you can have multiple methods with the same name, but different implementations. This can be useful in order to avoid inadvertently stepping on another method with the same name in an overcrowded helper namespace. More interestingly, you can have generically named helper methods with implementations appropriate for different model classes.
