That window design looks like it would never seal properly.
Here in Germany any window from the last 30 years or more will not let any air in when its fully closed.
And how is it sealed on the sides and the top?
European casement windows actually get pulled into the frame (and seals) all around the frame by rollers which move sideways along sloped ridges when you move the hinge to the closed position.
But will there still be air coming through when there is wind pushing on that side of the house?
I guess they are kind of complicated, but energy efficient windows make it possible to increase the window area and size without losing too much heat.
Energy is also more expensive over here, which probably helps in that decision, as the cost of these windows can be easily recouped in a few years just by needing less energy to heat the house.

Why wouldn’t it seal?
Because its not possible to pull the window into the seal when the window also needs to move up and down.
The seal is on the bottom so it just falls into it using gravity

The window stays sealed on all other sides. It just slides up and down. Windows in Europe sound needlessly complicated

Americans houses aren’t windy inside, no.
