Yeah, I am regularly confused by it. I prefer having my maximized windows as normal windows in a virtual desktop. I can then minimize them and work with the windows below as usual. The MacOS approach is very different in that regard. I prefer managing virtual desktops myself, as it allows me to organize stuff and allows me to keep a simple overview of my virtual working layout in the back of my head. Dynamically changing the amount of virtual desktops/maximized windows is just too counterintuitive for my taste.
