I do not understand what he means " automatically fill a selection: tool where upon lifting/closing the selection" The Free form Pen tool when set to Shape mode cam fill and stroke am new shape layer with sa solid fill or patter fill. I do not know if that is what he is looking for.. Also though the selection seem to be close for the fill the automatic selection close does not seen to be stroked. You also can not target a layer mask like you can with the lasso tool.
