I assume so. I didn't even notice that the article didn't motivate that `async: false` is bad. I always avoid it if I can since you might as well perform independent tests concurrently.
From the docs [1]:
* `:async` - configures tests in this module to run concurrently with tests in other modules. Tests in the same module never run concurrently. It should be enabled only if tests do not change any global state. Defaults to `false`.
