They might be referring to how clicks don't register with an app until it has focus (the first click being to focus it).

On Windows you can, say, click once to pause on a video playing in a browser window that doesn't have focus but is visible. On macOS, it's two clicks, because you have to focus the app first.

I don't care for the behavior but it's so minor to me that it carries essentially no weight.

Ah! This does make sense. I mostly run things fullscreen on my laptop and use Mission Control to swap windows so I really only encounter this when my laptop is docked to a larger display.

It doesn't particularly bother me one way or the other to the point I didn't even think of this, despite also being a daily Windows users on my desktop computer.
