WASHINGTON - A Pentagon report on Guantanamo prison ordered by President Barack Obama concludes conditions for inmates are in line with Geneva Conventions and other legal obligations, a US official said Friday. The report was due to be delivered to the White House by Saturday as part of a landmark executive order issued by Obama last month mandating the closure of the "war on terror" detention camp. The official, who spoke to reporters on condition of anonymity, said the review conducted by Admiral Patrick Walsh found that detainees were treated humanely, in accordance with the Geneva Conventions and other laws recognized by the United States.
An official that spoke to reporters maintained anonymity because he or she spoke about a review conducted by Admiral Patrick Walsh about conditions at the Guantanamo prison. 
It's neither because we can't know why exactly anonymity was required by the speaker to the reporter.
