Did the AG ever say that? Or was that just a media invention? There would be hundreds of potential leads lurking in the files that hadn't been thoroughly investigated, him possibly being one of them.
I think the Portuguese were holding their cards very close to their chests and I think they are as capable as SY of spotting evidence which hadn't been followed through earlier in the inquiry which justified investigation.

Despite the scores of leads which have not been investigated properly, Portuguese Attorney General Pinto Monteiro dashed the McCanns’ hopes last week by saying the case would not be officially reopened, adding that no “credible” new facts had emerged during Scotland Yard’s year-long £2million investigative review of all known evidence.
Portuguese officers in Porto in northern Portugal have for some months been conducting a cold case review, liaising with Scotland Yard, but they are not making fresh inquiries.
Porto is a six-hour drive from Praia da Luz and it is not thought that any of the officers doing the review work have been active in Luz.
As the Yard unveiled a new “age progression” image of how Madeleine looks now, just before what would be her ninth birthday on May 12, there was no activity at all at the Policia Judiciaria headquarters in Porto last Wednesday.
As it was a national holiday the woman in charge of the Madeleine case, Helena Monteiro, was not even at her desk. She refused to give an interview and referred all inquiries to police in Lisbon.
At one point a noticeboard with the new image of Madeleine on it was seen being moved into a large office but one officer there said: “This is not a major investigation for us.”http://www.express.co.uk/news/uk/317111/Madeleine-McCann-The-lost-clues
