If I create a group of objects with a while loop

#declare Thing =
union {
 #declare a = 0;
   #while (a<10)
     #declare b = 0;
       #while (b<10)
         sphere{<a,b,0>,1}
       #declare b=b+1;
     #end
   #declare a=a+1;
 #end
}

and then intersected my new object Thing with a plane

intesection {
 object{ Thing }
  plane {y,0 }
}

would the intersection testing be done only to those objects that the
plane actually comes in contact with or would the intersection testing
be done against every object in the object Thing ?
