But it is kinda obvious, since this is how unpassable terrain interracts with everything. If you use an ability that would move you (Flash i.e) it will push you forward if the ability can take you more than halfway through (or something like that), making you travel farther than the ability's own range.

So the same naturally goes with objects that you can place, from wards to Heim's turrets and Teemo's Shrooms and so on. Since they can't be inside the terrain they will be pushed out to the closest passable terrain.

And really, he's not being an asshole, rather just amazed over the fact that something that was so clear, to him wasn't common knowledge. Which is a perfectly fine way to feel about this.
