Eh. There are lots of reasons writers use pseudonyms. Separation of their day to day life from their writing life (one author I can't think of ATM did that because her academic coworkers would look down on the stuff she writes). Keeping writing that would appeal to different audiences easy to differentiate (Seanan McGuire does this, her zombie books are under the name Mira Grant). Searchability (whenever I am ready to publish something this will be my reason because my real name is far too common, winning the SEO war is almost impossible). Obviously this is the reason Rowling did it with her recently uncovered book, but plenty of other reasons exist to use pseudonyms, both for existing and new writers.
