It had a grace period where if the target died within .5 seconds after you used it, it would refresh.

It doesn't seem like much, but it meant his ult refreshed even if someone stole his kill in that time period, and especially skilled players abused his W (it resets the AA timer) in case the ult itself wasn't enough to guarantee a kill anyways.

Summing up, .5 grace period was enough for it to refresh far more than Riot intended.
