Kayle Shield stopping projectiles like Braum shield

So there I was, I had 6 Sorcerer team with a Varus. The enemy had a Kayle. Their units were in a direct line from my Varus. Kayle shields the unit closest to varus, my varus taking a generous 4 seconds to fire his arrow. When he lets the arrow loose, he fired it directly at the kayle shielded unit. It pays through the shielded character harmlessly, then all the characters behind the shielded character feel the breeze of the arrow as it sails through their skulls dealing no damage. I understand the shielded unit shouldn't take any damage, but all the units behind it should've since the animation of the arrow continued (unlike a braum shield which absorbs projectiles.) But nary a unit took damage from 2 varus arrows due to the kayle shield. Is it supposed to behave like a braum shield? At least don't have the animation of the arrow harmlessly passing through the whole team. Have it stop like the braum shield.
