What's the point with that quite lackluster story in Endwalker?

[Kazemon15]

Would you rather he actually sundered Ryne to show how it worked? Or have you considered that maybe he just knows that there is a good chance that we will not understand the details of sundering? Do you always take everything you see at absolute face value without putting a bit of thought into it?

I don't understand what you mean by this? I absolutely do not see "everything at face value." Just because I don't agree with your interpretation of what the story means does not mean I "don't put thought" into what the story is trying to say.
