Does Exhaust work post-ability usage? As in, for channels or abilities that do not do damage instantly, can using an exhaust lower the damage output after the fact? For example.. - Katarina ult - Nunu ult - Wukong ult - Anivia ult - Karthus ult

and many more. Is there a point to exhausting them to lower damage, or does it only work an any spells cast in the future?
