I recently played a game where I was playing Master Yi. There was a low health enemy champ getting hit by the turret, but still had health. I Qed him and the animation and sounds went off. I exited the Q and then the turret hit Bard again and it was an execution, not a kill.
Bug.
As an avid Master Yi player (200 games overall at least), I can confirm this is intentional and not a bug. Annoying, though. If the tower shot hit Bard during the animation of your Q, but before the entire animation was done, it wouldn't deal any dmg and would place you in your original location, even though it looked like it went through. The damage doesn't go through until you're completely finished with the animation, so this occasionally happens, and annoys the crap out of the Yi player.
Yeah :/ Hope my explanation helped, though!
