If a technique can be used in many different ways, it will require many different "set ups". Unfortunately, the form/kata can only "record" 1 set up.
Will both follow on moves (after downward parry) be recorded in the form/kata? The chance is very small.
These comments show you don't understand what kata is and how Bunkai is studied, I think you are jumping on the bandwagon of slagging kata off because you think it sounds cool to. Explanations are been given time and time again but you don't want to understand what kata or Bunkai is, as for the comment about the 'worship' of kata that is verging on being insulting. I will say nothing more than it's very disappointing that a martial artist's cup is full and brings it here overflowing.
