I think this was originally the advertising slogan of Coca-Cola Company, and someone changed it. No wonder some people say it's a fake slogan. The first word of the advertising slogan of Coca-cola Company should be Coca, and the second word should be Cola. The advertising slogan is Coca-Cola. There is another sentence behind, which is true. It probably means "this is the real thing". Someone changed the position of these two words, put Coca after Cola, and changed them all. Change the slogan "It's the real thing." The president of Coca-Cola Company said, "It's true." (It's really nothing. There is a word in the sentence. Rual is true in the advertising slogan of Coca-Cola Company.

Enjoy Coca-Cola. It's true. Enjoy Coca Cola! It's the real thing! (Enjoy, enjoy)

You can search the English advertisements of Coca-Cola Company on the Internet and compare them carefully. I believe you can find the answer yourself.
