[Gameplay] When walking over Veigar's prepping stun wall, caused execute death to be a kill

Playing against a , a day or so ago (ARAM) I was walking to the nexus towers to get an execute, rather than a kill (yea, I'm one of those people). I thought I had successfully been executed after the final turret hit. Much to my surprise (and may I say dismay) I was not executed, but killed due to the stunwall's Status Effect.

If I would have been stunned, I would understand, and would have just said "dammit" and moved on. The problem is, I wasn't stunned. I walked over the wall, ever so carefully, while it was still prepping for the "hit", in hopes to evade the stun and get the execute. It seems I hit either a timing edge case, where the kill is granted due to me walking out of the stun, or I hit a different case where the stun wall's prep causes the "kill" condition with the status effect.

With most champions this wouldn't be as big of a deal, but I feel that with Veigar, it is a bit more important, due to his scaling on take downs. Hopefully this is enough info to test/verify this. Even more hopefully, this is just a fluke and I experienced packet loss making it look like I was out, even though I was actually stunned.
