I'd vote that technically the guy is correct, but it's just a technicality if the card is advertised and shown as being entombed as authentic. Even if my view is correct, this falls under no harm, no foul.

I note that, personally, I've always considered a trimmed or otherwise altered card as a grade of Poor. But the grading companies don't do it that way (which would circle around to why I said the guy is technically correct).
