That will work except > when the overlay has two properties that contain strings that are eq. This would be a real pain. What if the string being displayed is a display property on the before-string? The experiments don't need to handle such complex cases in order to serve their purpose: to figure out the right criteria for which overlays' properties should influence which overlays' strings. Once we are confident of the right criteria, we could implement them cleanly and reliably and efficiently.
