Ivern Bush + Ward interactions

This is going to be difficult to ask properly without a drawing, but I'll do my best:

Currently, when you place a ward in a bush, it gives vision of the entire bush because the line of contact is straight (think about the side bushes in mid lane, a ward in there gives vision of the entire bush because it is straight). The only place I can think where a ward doesn't give vision of the entire bush is at Red Buff, but that's because the terrain is curved and therefor blocks a ward's vision if placed at either end of the bush. At the same time, wards in 1 bush do not grant vision of other bushes nearby if it's not connected, (think about the death bush in the river and the nearby bush going into blue sides).

So, theoretically, an Ivern could place a bush that connects with one of the Mid Lane bushes at the very end (creating an "L") and so long as the enemy's ward is not on that corner, they would not have vision inside of that bush right?
