Here’s an example of a feature enabled by the startup notification protocol.

When a user clicks on an icon for an application in a desktop’s launcher, the launcher will provide feedback to the user that something is happening, perhaps by changing the pointer to the “busy” indicator.  That feedback will be cleared once the application displays a window.  For the launcher to know when to clear the feedback, it needs to know that a particular window is associated with a particular application launch.

So, in the case you describe, where the user goes on to display other buffers, nothing happens, and that’s fine.
