You could have multiple slabs above a wall (ceiling, structural slab, floor/ceiling framing, floor finish, etc).
And these slabs may not even extend over the walls.
So you would have to link every wall to a specific slab on each storey.
It is much easier to use a storey height with an offset.
The storey height applies to every wall.
