Joh-dan, Upper sward style

Joh-dan form, Over head sward stance is very aggressive one.
It is said to be "Hi-no-kamae (Stance of Fire)"
Upper sward style enable to give a quick shot.
But it's risky when he missed hitting since he usually give a shot using only left hand, so after giving a shot, he is very weak against attacking. 
Furthermore, opponent player can hit left hand that is in upper sward style.

Upper versus Upper looks like there are few chance to attack each other.
After attacking, they must repair their form for next shot.  

 

I wonder this match called an attention to people.
I have met two swards style one only a few times. All they were high grade Sensei, Ken-doh master.
