You seem determined to miss the point. The sender sends two identical
copies. Royal Mail delivers both of the letters. The addressee can bin
one because the paper bears the same ink marks as the other one.

In my analogy, the company sent two identical copies. They are
identical by definition, printed with copies=3 (one for them to file).

Similarly, the bodies of the two emails are identical. They are cloned
when they're sent by exim. Look, here is the cloning in action
