It's a misconception
He explained in an sbs that the one piece will be found in 5 years
There's still dozens of possible plot lines after luffy becomes pirate king

I 100% think Oda is separating the final war from the actual Journey. Point in case, he's actually called the 100 chapters from Amazon Lily/Impel Down/Marineford as a side story, not the actual journey. As such, the final war and end plot isn't "really" the journey.
It also just makes sense too, because Whitebeard essentially spoiled how its gonna go down:
It essentially points to the structure: Find all Road Poneglyphs -> Lodestar/Laugh Tale -> Final War.
Tldr: 5 years left imo ONLY ever meant Luffys journey to Laugh Tale and One Piece, not the massive final war that probably be longer than Wano at this rate, considering it requires like 5x the characters.
