Your comment quotes an HN guideline, and my point relates to it. Some users may feel the need to create throwaway accounts in order to post comments that in an alternative reality they could post under their primary account and later delete if desired. It may not stop a scrupulous collector of data, but such a scenario may not be the object of their worry.
Drawing this into the logical conclusion, a user may opt to always post under a throwaway account, to avoid any possible tainting associated with a primary account.
