Jhin infinite 4th bullets with Morde

Basically my team's Jhin was ulted by morde and was killed. It summoned the spooky ghost Jhin but since Jhin was on his final shot so was the ghost. The ghost Jhin did not reload though, every shot was a 4th shot giving all of the perks when hitting an enemy. It also made it so he was just wailing on towers without reloading.
