Not GP, but there's a trend of auto-generated articles being spammed like "the best _X_ of [current year]" and they are rarely of decent quality (the current jetpens one is an exception).
This rule would avoid these articles, and GP probably sees the few false positives as an acceptable tradeoff.
Still seems like a bad fit for a HN filtering rule.
The spammy articles won't make the HN front page (at least not with the original title), but there will be a lot of false positives from the HN style of tagging older articles with the publication year.
