It reveals the Hypocrite that Osama was! Are you seriously asking why this is important information..it makes a big difference when an army finds that its highest and most revered General is a fake and not completely sold out to the cause. Its kinda like learning (post election) that your president or commander in chief isn’t eligible to be that…or that he is actually a Maoist plant to destroy and usurp everything good and decent about that country…oh wait….
Then also consider that before the 19 9-11 hijackers went to their deaths they spent nights at strips clubs getting drunk and whoring. So much for the piety and morality of the Death Cult.
Important to who?
We already know that they are hypocrites. His people don't believe he is dead. Do you honestly think they will believe we found this in his pad? PPPPLLLLEEEAAASSSEE.
