Discussion of Problem 1051. Simple Game on a Grid

I cannot understand
Posted by npenate 23 May 2011 02:35
Actually I can not understand the problem, as I understand it almost always the answer will be 1.
  Even in the example for me is 1 response:
     2 and 3 = 1.

  x stones intact
  0 stones removed

  x x x x
  x x x x
  x x x x

-> _ 0 0 0 x
     x x x x
     x x x x

-> _ 0 0 0 x
   _ 0 0 0 x
   x x x x

-> _ 0 0 0 x
   _ 0 0 0 x
   _ 0 0 0 x

-> _ 0 0 0 _
   _ 0 0 0 0
   _ 0 0 0 0
           x
   I know I'm wrong, but I do not understand. help me please.
sorry for my English.
