The hash at the end of the URL is actually the article ID, the part before that is just for SEO/readability, and has no affect on loading the article.

e.g.: omitting the article title from the URL still works (https://medium.com/@soleoshao/cd29c0713cad) as does changing it to something else entirely (https://medium.com/@soleoshao/i-like-turtles-cd29c0713cad)

Both those URLs still load the article in question.
