Just looking at the textbook again shows a different thing altogether. It shows the double knifehand block simply blocking a midsection punch (no trapping involved) then the second side kick to the throat of the opponent.
So much for clarity.
That's not bunhae. That's the official KKW explanation, which has little to do with any actual analysis of the movements derived from Okinawan kata.
Bunhae does not mean "application".
Right, and this is all too commonly the case with the Korean forms... they have in many cases been changed to conform to an 'über-rule', a stylistic requirement that bears little or no relationship to combat reality, and therefore make little sense in terms of practical use (as per a lot of the 'official KKW explanations'). A good, very sobering exercise is to look at the Korean versions of the old Okinawan kata, such as Empi, which becomes Eunbi, and see how the superficial resemblance is underlain by certain critical differences that drastically reduce the combat effectiveness of the system and make no sense in those terms. The replacement of the knee-strike-to-abdomen/groin strike sequence in Empi with a high front kick (supposedly carried out while you're pulling the attacker close to your body!) is a perfect example... the inevitable outcome of the Okinawan-to-Korean form translation rule that you replace knee strikes with foot-strikes, and the higher the better.
I would really hope that this kind of thing could be reversed, but after seeing those vids of Chloe Bruce, and of the new KKW forms that were posted a few weeks ago, I think that if anything it's going to get way worse than it is now. As long as you stick with the WTF scoring protocols, this is what's going to happen...
