Does Casey Stoner have a “Hanseung” in his name?

I ask because on Wikipedia it says Casey Joel Hanseung Stoner, I’ve seen him called Casey Joel Stoner, actually though I’ve never seen Hanseung in his name.

This is odd also because Hanseung sounds like East Asian and specifically like a Korean name, and Casey is Anglo-Australian. So I’m curious on why his Wikipedia says that, is it just an error or is it legit.
