I've never seen a center set up in a tail stock chuck like that before. That's different?

I was perusing a Tubalcain video today and noted he points to the same center you asked about. I just used it in the lathe chuck vs the drill press chuck, where it was about 5 minutes earlier. Handy little center. Check out at the 4:00 minute mark here.
Cheers,
