Before, After yet we forget during. He was tasked with destroying it, yes? He was given relics to help him, yes? He could've been titled with, "the Abysswalker" as he journeyed to fight the Abyss. He was given the pendant etc. as he traversed the Abyss and when he successfully did without succumbing to it, he was given the honorary title.

It could also hold truth that he was given that title after withstanding the power of the Abyss and traversing it without being swallowed up by it, he was given the title after he was Bested by Manus or his departure. It isn't uncommon to title someone with a name relating to their current quest. Dragonslayer, Lord's Blade, they could too have been given to their owners during their time in the Great War.

i think several movies n books follow the same tradition of an honorary knight's quest.
