The ground that is being fired at in that video is uneven. The grenade is rebounding in a direction that corresponds to the angle of the terrain it hits. The terrain physics behave this way in all Unreal based games.
Edit: Was that a response to Derpy Hooves?
You could try this on even ground and you'd get the same problem.
When you aim at something, the game draws a line from your weapon to that exact pixel you're aiming at. This is what causes the angle. The closer the enemy is, the smaller the angle is between the front of your chassis and the projectile trajectory.
The GL is different because it's affected by gravity, but fire a TOW or any other projectile moving in a straight line, and you will always hit the pixel you're aiming at. The problem is that this is counterproductive with a slow projectile at close ranges.
