I'll Decide ...
I would take that to mean that after making a save (and assuming the ball does not remain between the hands or between the hand and any surface) the goalkeeper is not considered to have released the ball (since he did not have control of the ball in the first place) so the prohibition on touching it again before another player has done so, would not apply.
I don't think this will really change anything much in the way most referees would handle the situation, it's just that the word "parrying" doesn't appear in the laws any more.
I think that's exactly what it means. Basically, the keeper can make a save (or "parry") and in doing so is not considered to still be in control of the ball. Seems sensible to be honest.
