I agree. And further (this is the point which you stil don't get), the string 'brown' and the string 'brown' are ALSO two distinct and different things which are not redundant with respect to each other if they represent two distinct and different logical propositions.

It is when you update every 'brown' to 'nworb' and in the process, also change all the last names which happened to be 'brown' to 'nworb' when you only meant to change the instances of the paint color.
