Well, you'd want it to display when you moved to the buffer - If you are
moving out of the overlay in question with C-x o it may not matter, but if
you are moving into a window with a buffer that the point is in one of these
overlays you'd want the action to trigger and display the error message.
The same applies to C-x b. This was just the use case I had in mind - there
are probably others.
