Best to follow the guidelines (although you'll notice they mention a few occasions where the original title might be replaced - mostly for clickbait reasons).

For past stories, it's not always easy to tell what happened at the time. One of the other guidelines Please submit the original source. If a post reports on something found on another site, submit the latter can lead to a submission URL getting changed later without the title being updated (and so in retrospect the title doesn't seem to match).

In that particular case @wokwokwok did point out the submission had the wrong title, although perhaps they didn't email the mods to ask for a title update.
