What triggers Shulk's alternate counter?

As seen in Shulk's trailer, Shulk's counter (Vision) has two attacks to it. But, when I use it, the first one is the one that shows up. How do I trigger the second one?


If you hold the analog stick in the direction the attack is coming from as it connects while Shulk is in his counter stance, Shulk will use his faster dash counter.
