I don't really understand why Khazna would abandon the momentum of his strike to grab a sword even further away from his enemy once he's already inside his guard. Also, it's a little harsh to suggest Metz was ignoring the particles, you said they were only beginning to form when your sword passed through them. It was a bit of a leap from beginning to form to fully formed when my post was technically an interrupt, but whatever.

He did it preemptively before he entered his guard. Thus forcing him to bypass the second swords tip. Also the blades form very quickly, (four formed in the time it took for your lightening to reach) he cut before coming into range previously.
