It was only 50/50 if you admit that that offensive player was going to hit the goile no matter what happened, her failure to pull up was dangerous to the keeper as she was going to run her through weather she caught it or not and that is dangerous.
Basic Definition of dangerous play (the part in quotes is right from 08-09 FIFA rule book): Any action by a player that is unsafe to him or another player, in the judgment of the referee. When contact is made, the referee will consider whether it was "careless, reckless or there was excessive force".
In fact after watching the video several time I would say the keep was in position and ready to capture the ball when the offensive player iniated contact with her. There was no way the striker was going to get the shot without slaming into keeper. That is what makes it reckless! I can understand the no call by the refs as they do not want to "impact" the game but this one is a no brainer. IF the play was at other end of field I am sure the other team would feel cheated too.
