possible kled bug?

after finishing kleds first hp bar he seems to have an effect similar to shaco's ult where he leaves the map. at this moment if you are attacking kled you will start to move in the direction/aa the next closest thing for example the ward that kled is able to place while he has left the map or any minion nearby. i feel like if you are attacking kled and he leaves the map then it should either stop you in place or keep you walking/aa kled not run away from him. at a minimum i don't think kled should be able to cast wards while he isn't in the map. any other opinions or explanations on this? i don't know if the developers intended for this to happen but its a pain to deal with him already i don't need to run away from him to kill a wards he has dropped after finally dropping his first hp bar.
