Hello, thanks for your comments. In general, NULL is null, you can't replace that with text or any other value, it stands as it is. However, this article focuses for BI/Data warehouse experts, and they surely know working with BI tool like SSAS (Tabular/multidimensional) must need to handle NULL value and translate that to something meaningful so that your model doesn't break and end user report looks meaningful.
