Not quite accurate.

Saving some view as a default will not affect any windows which are already sporting their own *custom* view. For those, one would need to manually clear out that customization. I.e., one-by-one... open their view options and (by holding the option key, to toggle 'Use as Defaults') click on Restore to Defaults.
