Well, it's an order of magnitude closer than the 355K that was predicted without accounting for relativity, and I think the point was that a melting point of 355K (82C) means it would be solid at room temperature, while 250K (-23C) means it is liquid at room temperature, so they can conclude it's the relativistic effect that's responsible for its weirdness. tl;dr: close enough.
