Radahn's BS Hitbox

I personally fought Radahn for more than 100 times before the nerf, and never witnessed something related to a sword hitbox problem (not a fan of the previous 40 percent decrease), but he certainly had hitbox issues with some of the shockwave attacks, and I think this is the most absurd one.
From what I can tell, the shockwave he creates isn't tied to where he's looking, but it's rather tied to where your character is. You can see that no shockwave comes out in the direction he's facing, but when I get hit, I have some kind of gravity effect on my left side. This is fairly bad, but the worse is that you can't even see the shockwave.
Btw, this is the latest patch (it was 1.03 when this video got uploaded), so it's still not fixed.
