Leica Camera Germany only means that Leica Camera is a firm enlisted in Germany.
Even Made in Germany would not mean much as german as european regulation on this matter is so vague, that in your case the lens to be inspected for image quality would be sufficient.
On the other hand such vagueness would give way for consumers or competitors to go to court...
But with a history of optical manufacture in both countries, who, except you, cares in such case anyway?
And even the famous JCII sticker had been applied to cameras manufactured outside Japan.
