If Pycelle tells Cersei Dorne and Varys says Greyjoy and Littlefinger says Vale then that’s a problem as Cersei won’t act on the information. It also might make her suspect misinformation as there are three different values coming to her at once and she’ll have to deduce what’s more likely that all three informants are lying, or misunderstand, or Tyrion fed them bad info. Much more likely to have three independent stories so that the traitors will be revealed even if there are multiples. In the current scenario, if Varys and Littlefinger snitch then Tyrion won’t know because Cersei will hear Greyjoy and Vale and not reveal what she knows to Tyrion because it conflicts as Myrcella can’t be married to two different groups. The better scenario would be something like “Myrcella marries Dorne to Pycelle; 1,000 ships sent to Westeros to Varys; I’m appointing Jaime as lord of casterly rock” then each betrayal could be known. If Varys and Littlefinger snitch in this scenario Cersei will look into ships and casterly rock and reveal the betrayers to Tyrion.
