Usyk made an adjustment, he moved further across to Fury’s left and that took the the uppercut to the body away from Fury as the centre line had moved and he couldn’t throw it straight anymore.
Usyk had superior footwork so he was always able to stay in that position. It seemed to me that Fury wasted several rounds trying to make Usyk walk onto a check hook in the corner too but Usyk wasn’t buying it, then Fury’s corner were giving him bad advice seemingly because his dad is a big loud dickhead people are afraid to say no to.
