A few reasons. Conceptually it is like an award for winning awards, not unlike the award for outstanding achievement in the field of excellence. It's weird that the IIHF created it and promotes it when one of the accomplishments is not connected to the IIHF at all. It's very odd to include one domestic league championship with two international accomplishments. It's a pretty blatant attempt to promote the IIHF's main tournament (World Championships) by associating it with two far bigger brands in the Olympics and the Stanley Cup that the IIHF doesn't control.
It would make a lot more sense if it was something like IIHF U18, U20 and WC, or even WJC, U20 and Olympics. If it gets more players to agree to play in the World Championships then that's fine, there's certainly no harm there, but it consistently causes my eyes to roll.
Datsyuk is not a diver of note.
