The blade literally hasn't breached Sigurd's guard though, I just explained how that would be impossible at the current proximity due to the length of the weapon. The fact that you just said you thought the weapon was six feet long and yet it's clearly labelled as eight feet long in the CS proves your misinterpreting the situation. 

I'll happily ask Drifting Pollen to interpret the situation, honestly I can only assume I must be misreading it somehow because it's literally impossible in my mind unless your character has inhuman strength, which I'm starting to assume she must have considering she outpaced Sigurd's sword strike with a fifteen pound shield.
