Poppy's w kills yorick's walkers [GAMEPLAY]

I have faced many Poppy's as Yorick, but I only recently noticed that a weird interaction happened. I do not think this is intentional because it makes no sense to me. if poppy activates her W while Yorick sends his walkers to leap onto the target wit his E, the walkers just disappear or die as soon as they hit the border. it does make sense that they cannot leap into the circle, although why would they die? when you try to dash on to her you are stopped at the border of the circle and the dash effect is cancelled but you don't die. why would the walkers die then? It is very frustrating to lose an opportunity to fight poppy or perhaps kill her when your walkers just evaporate as they hit her W. It leaves you unharmed and weak and gives her the opportunity to perhaps all in you and kill you. If at least they wouldn't die but get their dashes cancelled like it should be it at least wouldn't put you in a position weakness.
