To be fair he mentions it after realiseing that closed off areas, you dont need complex puzzles to get where you want to go, you can simply figour out how to go around or climb around it.
He means that in quantum break, you had to think of a solution to get ahead, and often times, the solutions didnt seem apparent.
Hes talking about the platforming in Uncharted vs Quantum break.
Seems like he thinks the Uncharted platforming is better.
He says that ("ps4>xb1, lets get real") right after mentioning how cool the climbing in UC4 is.
