Shaco R

I was playing some shaco last game, and I noticed when I used his ult, autoattacks still leaked through. I first noticed when I went to attack nasus, He began his Q animation and I used the ult and it still hit me, so I saw my healthbar at ~700 before I split, but after I split both the clone and I had ~400 hp. Again, this happened when I was fighting xin in the jg. I let him hit me twice with his Q enhanced attacks, used ult, but his attack still went through and knocked me up. I was still knocked up after the split. It feels like Master Yi Alpha strike tbh. Maybe I'm just bad at timing or they added a longer delay? I don't know.
