  Wrong.

union
{ object { Object1 }
  union // sub
  { object { SubObject1 }
    object { SubObject2 }
    union // subsub
    { object { SubSubObject 1 }
      object { SubSubObject 2 translate y /*this affects only this object*/}
      translate -y // this affects all objects in this 'subsub' union
    }
    translate x // this affects all objects in this 'sub' union
  }
  translate z // this affects all the objects
}
