Is it a matter of the active window, foreground window or the current thread being foreground? The active Window (Get/SetActiveWindow) is a per-thread property and the foreground window the desktop-global properly. Afaiu a window can be active for the current thread without being the foreground window.
One way to test this would be to create a third window on the same thread and make it the foreground window instead of the desktop window. I don't remember exactly what happens when you call SetForegroundWindow(desktop); SetActiveWindow(device_window). I assume it makes the test behave differently, which is why you use SW_SHOWNOACTIVATE.
If what I wrote is complete junk ignore me. It's been a few years since I worked on the alt-tab stuff...
