Steps:
1. Get hit twice by Knock

When you get hit by Knock a debuff is applied that causes the next hit to deal additional damage, but in this case, the first hit(normal damage) came after the 2nd hit(damage increased due to debuff). Which in: https://clips.twitch.tv/FineColdbloodedPotatoM4xHeh shows that the damage taken was 300k followed by 1.6k rather than 1.6k followed by 300k as intended by the mechanic.
