its for humans I would expect, to know what the page refers to without opening it.

Kinda smart.

Also; taking it from the end means you only need to parse the string as an offset from the end. It can make load balancing much faster in theory.

It's also for crawlers. When doing technical SEO, having a human readable slug in the URL is low hanging fruit that is often overlooked. This, as well as having a <title> structure of `CURRENT_CONTENT_TITLE | WEBSITE_NAME` are things that are quite trivial to implement and provide a significant uplift in both SEO and UX.
