[Gameplay] Multiple Hecarim Dashes

Not sure wheter i should call it a bug or not, but it surely is a weird interaction. Whenever Hecarim uses his e to dash to a target, but the target dies before the real impact (before hecarim actually deals damage to the target) he may dash to another target. So it isnt really a bug, because he doesnt deal the damage twice or applies the knockback twice, but still it can be used (mainly in combination with smite) to close a big gap. e.g. if you chase somebody through the lane you can dash towards a minion and smite him right before you hit him and dash afterwards again onto the enemy champ or whatever. Explanation to the video: I used my e and waited for the exact second, that one of my minions would finish an enemy minion to dash on it. Then i dashed to another minion smiting it right before the impact and finally i used "the real" dash onto a full hp minion. Whereas only the last minion got the dmg and the knockback effect, but still i moved extremly fast by just using my e dash multiple times.

I know that this is not game breaking or something, but I still want your opinion if its either a) a bug that should be fixed soon or b) an advanced hecarim mechanic / trick that should not be changed (see poll)
