because it allows me to choose if I have to see the nonsense you post, for example I will not read any of the frankly dull "look it me2 posting you do on the transfer thread
it's nice
Basically if you mishit a pen to one side, as long as it is on target you have scored if the keeper goes the wrong way.
Panenka it and mishit and as seen today the keeper can readjust and save it.
This, as it allows the keeper a chance to correct his actions and still save the pen. There's a reason you don't see it as much as more conventional penalties.
