I can be behind a pillar and he can swing his sword or perilous thrust through/it. Also there is a annoying move it does that looks punish because he winds up his sword for so long. If you do nothing he just chops, but if you go to punish her with start swinging around.
I do think it funny that if you thrust he will counter like you can.
Oooooh, the second fight. I thought you were talking about the first fight.
For the wind-up move, you can time it by either 2 slashes and then dodge to the side, or you can wait until the sword is overhead before dodging to the side. The timing is tricky.

You'll also notice sometimes I'm swinging my sword in thin air (not when he jumps away, those are genuine mistakes). I actually do that as a defense since he sometimes runs into my sword swings, or I catch him as he's about to do his sweep attack. It just completely catches him off guard.
Also, don't worry too much about catching him with the head stomp if he tries to sweep. I got lucky on mine and manage to stomp him. Try to hold your stick to the bottom left when jumping to try and catch him with the stomp.
also notice how I try to move around to be away from the pillars, cause if your back is against the pillar, the camera goes bonkers. When I caught him in the corner, you'll notice I briefly lost track of him due to lock-on couldn't keep up with him. That got hairy, but I was able to quickly regain control and move out of the corner.
