Typically that's how they were made, they only engaged the lug races they're length in the receiver ring.
If you look you can see the back of lug is just outside the ring, the forward portion is touching or almost touching the barrel tenon. I only use those tools for swaps after the factory Igore tightened barrel(s) are pulled. For those I use a different setup-tools, no barrel vise either way.
