Agree I'm not a face recognition expert but from the linked stories photos The Forehead, Cheekbones, Lips and most definitely the chin are to me visibly different.
The output from the system the "Investigative lead report" has a digital image examiner named who should be trained in recognising such discrepancies and should have withheld the report until they could be certain they were a 99% match. Or at least explaining why the match was made if it was so different.
It may be that the photos are of the arrested person as a younger chap without tattoos but this should be part of the scoring.
