Sure they were. They had identical body positions up until they landed. When they landed both turned to the left, yet Shields continued in a straight line, while Dez went from facing forward toward the goal line to way left for the pylon.
Dez started his jump about the 10 yards line. Sheilds kept going and was ahead of Dez when he started his jump about the 7 yard line. That alone negates any argument that they did everything identically.
In addition, Sheilds, being ahead, was reaching back for the ball, and Dez, being behind because he started his jump 3 yards sooner, was reaching forward for the ball. The way they each reached for the ball also negates any argument that they did things identically.
Then, when they came down, Dez landed on his left foot, and Shields landed on his right, which also affects body position and the direction of the fall.
And Dez jumped much higher than Sheilds, probably at least a foot, and his legs were flailing and not coming down in a coordinated manner, where's Shields feet stayed at pretty much the same place in relation to each other as he jumped and came down, with his second foot hiting the ground in that same position just an instant after the first. In short, Dez stumbled on his path to the ground with his legs flailing, and Sheilds feet stayed in the same position as he jumped, landed and fell.
And, again, there is no dramatic difference in the direction they fell anyway. A slight angle of the foot as it hit the ground, or a give of the leg can easily have that much effect. And, of course, people don't necessarily stumble in a straight line.
