Xenon's Instant Shirk

Instant Shirk (Passive)
Dodge enemy attack again if the first dodge failed. The second dodge is based on fixed percentage and not affected by stats (LUK + Level). Also permanently increases Aegis System’s missile damage.
LV1: 21% Dodge Rate. +10% Aegis System Damage.
LV20: 50% Dodge Rate. +20% Aegis System Damage.

I dont really get what this means, can anyone confirm?

1) enemy hits xenon once, xenon's base dodge failed, it then triggers a secondary 50% dodge rate within that same enemy attack.

2) enemy hits xenon with a first hit, xenon's base dodge failed. enemy hits xenon a second time, xenon's 50% dodge rate from instant shirk activates.

cheers
