Bullet Lines are like a laser targeting system that shows the trajectory that bullets fired out of the gun will follow to other players. Though, whenever you focus on a target, you focus your eyes on where you will be targeting, so this can be used as a method to predict the trajectory too, but this method is NOT a Bullet Line. It's just making use of your battle experience and logic.

P.S. Please use shorter titles. Don't make the first sentence into a title...

Edit: If you want a quote that these two are different things:

"Even so, Kirito was able to accurately target the bullet that aimed for his left thigh with a flash of his lightsaber. That was not a gamble. Moreover, at this distance, this projectile velocity, Bullet Line assist would be useless. In the end why— How did he...?"

...

""...How did you predict my aim?" At the other end of the energy blade, he softly spoke; "Even through the scope's lens, I saw your eye." Eye. In other words— her line of sight. He read the bullet's path by her line of sight, was what Kirito meant. There was actually someone in this world who could do this. Sinon had never thought about this. A small tremble that was either terror or not travelled its way from her back to the top of her head."
