You have never had skills shots become invisible? His grenade will disappears after he throws and then boom it till there you just can't see it so it hits its target invisibly. I have had multiple occasions playing against heimer where his turrets completely ignored me when I was the only thing there and I was either attacking them or running past them.

With Renekton it's just basically like all the other on-next-hit abilities unless RIOT actually cleaned up their code on the newer releases the champion should stop attacking or pursuing or even moving unless you clicked at the destination while doing so when you active the ability.
