What if Snape's identity as Dumbledore's spy is protected by the 
Fidelius charm? As Secret Keeper,  Dumbledore  could reveal 
that Snape was a spy  to the court  at the Pensieve trials and still 
expect it to remain secret.The people  at the trials would never be 
able to tell anyone else what they'd heard. 

It also makes more sense out of the Occlumency bungle.  Snape 
can reveal himself "Yes, Potter, that is my job" without fear. 
Voldemort, even if he is occupying Harry's mind at that moment, 
will not find out. But the Secret Keeper is another matter, and this 
may be another reason that Dumbledore chose not to teach 
Occlumency to Harry himself.

GoF does say that Harry told Ron and Hermione about 
"everything Harry had seen in the Pensieve."  But if 
Dumbledore's words "and turned spy for us" were omitted   by 
the operation of Fidelius, would Harry even know?
