Legendary Zombie Brand Hidden Passive Glitch?!

Not sure how to replicate this one, but it appears that Brand, possibly just Zombie Brand, has a bug that makes his ult bounce EIGHT times (not counting the initial hit) instead of the described four hits in the spell text.

Here's a video!

In all honesty it's PROBABLY just a Brand bug and not a Zombie Brand bug, but hey, that makes it funnier! :D

Working as intended...LEGENDARY
