Blaser's brochure says;
"Free-floating Barrels
Both barrels can expand freely and independently of each other. On the double rifle, both barrels are supported inside a sleeve tube an can be adjusted to the same point of impact. The same applies to the rifle barrel on the rifle/shotgun-combination, making it easy to adjust it to the shotgun barrel, especially when shooting with slugs."

It doesn't say side to side or up and down, it says adjustable.
