Brian, you're describing the duplieren counter to this move. If you read any of the verses, such as von Danzig, it will describe more or less this same action. Because of this, one should never just press the hands and stay still, but should instead immediately withdraw with more final attacks. Also, you want to slice from below the hands to push them somewhat up first and then come downwards onto them, which will make it more difficult for the opponent to pull of the duplieren.
