Before:

  O . O # O . .    Upper left corner of board
  # # # # O . .    O, to play, needs a ko threat
  . . . . O . .
  O O O O O . .
  . . . . . . .

Black has three points of territory and two prisoners, making five.

White suicides three stones:

  . . . # O . .
  # # # # O . .
  . . . . O . .
  O O O O O . .
  . . . . . . .

and Black responds:

  . # . # O . .
  # # # # O . .
  . . . . O . .
  O O O O O . .
  . . . . . . .

Now Black has two points of territory and three prisoners, making five.
