Should be obvious: Because the intention of a given occurrence of `default-mode-line-format' might not be to set the default value of `mode-line-format'. Consider code that used, for example: (setq mode-line-format default-mode-line-format) A reasonable update of that code would likely be (setq mode-line-format (default-value 'mode-line-format)) That does not set the default value of `mode-line-format'.
