Crazy Vault: Full-Twisting Tsuk Double!

I just saw this video on GymnasticsCoaching.com and it's pretty insane. It's of an unidentified North Korean gymnast doing a Tsukahara double back with a full twist. Though he puts his hands down, it looks like he can make the skill. This video was from training, but it seems like it won't be long until this vault is competed.

Watch the video. (I wish I could embed it, sorry!)

I still get freaked out watching a lot of gymnasts' Tsuk doubles, so I for one, am a little nervous about seeing this one in a meet.
