Funny end-game visual (glitch?) for Jhin

Right before your team destroys the enemy nexus, activate your R. You'll still zoom out but you see their turret being destroyed and get the victory screen. I only tried this once, and I was at their nexus already so I don't know if you can do it farther back (like at your own), but I thought it was something worthy to speak up about. I tried saving a picture of it with the PrintScreen key, but apparently it shows up black. Darn.
