That 3yr / 5yr yield isn't that useful, but it does show that the 2yr / 10yr might be close to inverting. Plus the market believes the Fed is about to raise interest rates by +0.25%... but if the yield curve is almost inverted they might pause before doing that. I take the article to mean "watch out for 2yr / 10yr yield inversion and possible signs of a recession". But I don't think that's guaranteed.
