Retaliation ?

[Namonaki 73]

I have a question about this skill

When it's activated, there is a blue circle on the hud. It 5 seconds remain, ok that the skill duration, I understand

But after 5 seconds, the same symbol appear with the red circle displays as 8 seconds ? 

What is it ? the cooldown time ?
