You're right. But at the same time I wonder how many users understand the distinction. You can get 'rid' of a window by either hitting the red x (which I presume is the same as Ctrl-W), Alt-Clicking the dock icon (which I presume is the same as Ctrl-H) or going to Menu->Quit (Ctrl-Q). It's easy to understand this, once you realize that window management is app-centric and is organized by Application rather than individual windows but that's a subtle distinction most normal users will not understand on their own. To compound things, for some apps,closing the window will actually quit the app. And for some, closing the window leaves the app still running in the dock but clicking the dock icon doesn't bring up.
