I agree it could be better, but I can't answer for it. Best to search before submitting, especially if it's a news article that's more than a day old (although that doesn't always work with title-edits).
The account spams HN with dozens of (usually political or against HN guidelines) posts every single day of every single month of every single year, do you really think they care enough about what they're submitting to search?
Why didn't you search for it so you didn't submit yet another dupe?
