I've noticed that Confluence, Reddit, and a good number of news sites do the same thing. Usually the title segment is entirely ignored, meaning you can prank someone by changing the title part to something shocking, and it just redirects to the usual page, because the server only cared about the ID bit
The fact that so many sites do this (including "normie" news sites) shows that site designers clearly believe users want and expect "informational"/"denormalized" URLs, rather than /?id=123
The better way to implement this is to serve a 301 redirect if the words in the URL don't match the expected ones, that avoids trickery and also removes the risk of the same page being accidentally indexed as duplicate content.
