Yurchenko full on, lay 1/2
Round-off 1/1 on, layout half
Like the tuck 1/2, the layout 1/2 is an unseen, mysterious figure because it’s enough of a burden to deal with trying to wrench a salto out of the no-block you got after that full twist without also having to try to fit a 1/2 twist in there and a blind landing.
In terms of naming, you will mostly still hear this style of vault referred to as Yurchenko full ons, though the requirement of a full twist onto the vault is a leftover from the vaulting horse day, and now a “full-on” vault simply requires 3/4 or more of twisting onto the vault to count—much like the Tsukahara requires at least a 1/4 twist. You can see this push and pull in the code image itself, where the verbal description says 3/4 turn, but the image depicts a full turn.
The full-on vaults are very rare—because of being, you know, hard and complicated—and because it’s just quite difficult to get anything on that vault following a full twist. You’re not going to have much of a post-flight
