Count the points, before and after. It does lose a point.
  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.
But after dame filling, Black will need to capture the O's, losing
one point of territory...
So he will.  You and Mark are right.  My apologies.
