That is good advice - even if you are on solid legal footing, the presence of someone else in the market (even as a dead entity) with a too-similar name will cause issues around brand recognition, SEO, etc. And they can decide one day to use the domain they do own and put something up there that will cause confusion. They can't sue you, you can't sue them, but they can just be a pain. Sometimes the answer is not a legal one, but a practical one.
