It allows to reset prevent_medium_removal flag and "eject" the image. This can be useful to free the drive from a hunging host or if the host continues to use the drive even after unmounting (Linux does this). It's also a bit like using an unfolded paperclip on an optical drive. Previously, the undocumented method of sending SIGUSR1 to a special "file-storage" kernel thread could be used for these purposes, but when using multiple storages there was no way to distinguish one from the other, so we had to send a signal to everyone.
