Comment:

 Hi there and welcome to WordPress Trac!

 The value of `$original_slug` isn't the old slug of the post, but the
 original value of the `$slug` at the beginning of the
 `wp_unique_post_slug` function, before it was modified.

 When you edit the post in the editor, you tell WordPress your new slug. To
 make sure the new value is unique across posts, it's ran through
 `wp_unique_post_slug`. The old value of the slug is not involved in this
 process at all.
