with dots you are on borrowed time, the hits do half the dmg, the bleed does the other half, along with nobu doing more dmg to bleeding targets I also can't tell if this is a custom match where gear stats could apply. Ubisoft was shown and it was reported to countless times before the games release about this nobu bug... glad they didn't care to touch it, but they just had to botch gb.
Yeah it looks like that second bout of bleed is just a bug. You need to always be on your toes to dodge around the side of the Nobushi's kick. Always. It's really punishing to get hit by it, but once you don't, I *believe* it is freely punishable.
So again. Just deal with the mechanics.
Except the bug, that should be fixed.
