Fiddle passive bug

Fiddlestick's passive grants assits - which is fine, but it also grants kills - which is not fine. I was running away one day (about a week ago) and i wanted to die to a tower because I didn't want to feed a kill. I run away and nobody, I repeat NOBODY hit me with anything and fiddlesticks wasnt even close to me, i am almost dead but fiddle walks up and doesnt use any spells, doesnt even auto attack and the kill that should count as an execute goes to him, just because he walked up and his passive worked on me. that passive pls.
