Exactly. But given that Beni has been arguing in favor of Kreia throughout the debate, and insistent on shoehorning Revan into a 1v1 in the place she's most powerful...I think his decision was made a while back.
Except it was the only possible scenario for Revan to confront Traya. She is unlikely to leave Malachor, which means Revan has to confront her, per the Kaggath rules.
