Friend buying showcases and said this, is it true or worrisome?

I have a friend trying to get every showcase, and he is taking to a seller on I think the SWU FB trade group. Guy told him this, and it sounds sketchy to me? Is this true?

"With these SWU showcases, I like to be up front. These all of the soft rounded corners. The SOR ones came from the re-print wave, and don't have the sharp corners. I've had to have many convos about how this is perfectly normal, and not a sign the cards are fake."
