Yes. We simply refer to this as fraile. However, your original post described it originally against a vertical strike to the crown of the head. And based on your description now, it cannot be done as both you and your opponent are running vertical lines. Ah, so you were one of the very fortunate individuals to have learned directly from Tatang. I guess you were there alonside Mang Tony, Topher and the rest. I will be sure to let him know you were his peer. Are you now training with Mang Tony or Romy? I absolutely agree. The art is still being discovered by many worldwide. And is appreciated for its simplicity and effectiveness. As far as the "Art" revealing itself, that is also often a matter of a students diligence. I am sure you can attest to this as most of you were left to dissect Tatang's methods in an effort to decipher the actual techniques. I have of heard him ever being described as such.
