No, I read everything you said.
The statement that you made and that I quoted had no other word in it that would have changed its meaning. You simply said what I quoted and then went on to talk about how you don't get wrath stacks for taking damage. If there was some other intended meaning, it was either not stated or not stated clearly.

So then what you're saying is, Inner Beast and Vengeance can both do something to the damage you JUST took? Like they can go back in time and mitigate the damage you took, or do something upon activation that has an effect that scales off of the damage you took prior to activating them?

You should probably go reread what exactly those skills do.
