Well, I was just messing with the title, nowhere said this is the First Age version but if someone can call him Spirindel (or whatever silliness).
Anyway, there's one thing a bit confusing in that article. Beside The Light of Valinor they also mention Unexpected Courage as a way to negate the forced effect. At least that's what it seemed they're saying but surely it's not true right? Even when you immediately ready Glorfindel you still had exhausted him thus you raise your threat? So they probably just mention it as another way to do two things with him but in this case he still has to pay the price?
