The details of Voldemort's defeat were hardly worth discussing. Andy and Dumbledore had long since coordinated their stories, and Scrimgeour naturally knew that perfectly well. Everyone was just putting on a show.
The only thing that needed to be concealed was the matter of the Horcruxes.

All the goblins at Gringotts had been killed, while the Death Eaters who attacked Gringotts had vanished without a trace—burned to ashes by Fiendfyre.
There were no witnesses left alive!
