Frightening case of permanent shock loss?

[Buckerine11]

I've been thinking hard about possibly getting a transplant to fill in my hairline, and since I don't think I need that many grafts, I'm leaning towards FUE. But, from what I understand, FUE doesn't give as good of yield as strip, and I recently stumbled across a poor fellow's FUE results from Dr. Armani.

His results are 9 months post-op, and not only have his grafts not grown in, but he's lost a good chunk of his native hair behind his transplant. This guy's case pretty much made me rethink getting a transplant, and it gave me nightmares, as this would be absolutely unbearable.

Is this even possible with FUE? If so, how often would something like this occur? If any doctors can shed light into why this might or could happen, it'd be great.
