Well ye on a cosmic scale it 'doesn't matter' in the sense that the future is already set in stone. But it always was anyway. Just because some characters have seen some of the future doesn't take away from the drama and intrigue that happens on the journey to that future.

From a storytelling aspect it wasn't pointless at all. Zeke and Eren got new interactions with each other and with Grisha, which develops them as characters. Possibly even changes their motivations regarding what they're going to do and their opinions of Grisha, particularly in Zeke's case
