So you might also see a headline like "Dortmund's title hopes fade as Lewandowski scores hat-trick" => "Dortmund's chances of winning the Bundesliga became narrower, after Bayern won and Robert Lewandowski scored three goals (possibly against Dortmund)"
It's something native speakers often don't realise, but there's a lot of really specific stuff for healdines
A later sentence in the article is formed similarly and correctly uses "as" - "The runway also 'melted' at the RAF Brize Norton, military air base in Oxfordshire, west of London, on Monday as the UK struggled to cope with the weather."
I think this matters because some people on hackernews are not native English users. They may be legitimately confused or misled by typos that a native speaker would unconsciously correct.
