I think it's just that Samsung seemingly wants to capitalize off of Apples momentum. I get it, they all borrow from one another. But in the case of Samsung it's ironic because they spend so much money and marketing either bashing or comparing their phones to iPhones directly. It's basically in most of their commercials and advertising. So to then borrow or imitate things from the iPhone it can seem a little tongue in cheek.
Most of the stuff Samsung is advertising of their devices, the iPhone doesn't even have.
