Yeah, all it is talking about possession and avoiding unnecessary redundancies -- it's pretty straight-forward.
-If you have a "blue car" it's not important that you have a car, so much as you do a "blue" one. Obviously, if it's "blue", you have it.
-Like you said, unless you are some unfortunate perso,n you were endowed with two eyes, just like everyone else. Big deal. But if you have beautiful, brown eyes, then that's something worth talking about and stressing -- just like that car being a cool shade of blue.
