  Markus explained it well. You can also think about it this way:

#declare i=0;
#while(i<4)  // Make 4 copies of this:
                 merge { sphere { ... } }
 #declare i=i+1;
#end

  After parsing the result is:

                 merge { sphere { ... } }
                 merge { sphere { ... } }
                 merge { sphere { ... } }
                 merge { sphere { ... } }



  On the other hand:

merge {

#declare i=0;
#while(i<4)  // Make 4 copies of this:
                 sphere { ... }
 #declare i=i+1;
#end

}

  After parsing the result is:

merge {

                 sphere { ... }
                 sphere { ... }
                 sphere { ... }
                 sphere { ... }

}


  Sometimes the first behaviour is the wanted behaviour. For example:

union {

#declare i=0;
#while(i<4)  // Make 4 copies of this:
                 merge { sphere { ... } sphere { ... } }
 #declare i=i+1;
#end

}

  The result:

union {

                 merge { sphere { ... } sphere { ... } }
                 merge { sphere { ... } sphere { ... } }
                 merge { sphere { ... } sphere { ... } }
                 merge { sphere { ... } sphere { ... } }

}
