Good point. I also think it's confusing because it's from the point of view of the program instead of the user. I.e., the program is sending draw commands to some server to get rendered. But as a user, the IO devices that I interact with (keyboard, mouse, display) are the client that connect to some backend (whether a web server or a remote program).
