In the initial frame, we see one of the twins phasing through the floor, in front of Trinity and Morpheus. Trinity goes ahead along with the Keymaker while Morpheus stops and takes a katana. At this point in time, the twin who was phasing through the floor should have materialized above ground, putting him between Morpheus and Trinity/Keymaker. But instead we see Morpheus reunited with Trinity and the Keymaker.

If it's not obvious yet, Morpheus stuck his katana onto the side of the truck "at arms length", even if you accommodate his upper torso's length, he couldn't have stuck that for as far as he did when he stood on it.
