Star Trek DS9 - Inquisition 6x18 - Sloan talked to both Bashir and O'Brien at the same time?

There's a writing goof here that no one ever talks about, and I don't know if it's because no one noticed.

When O'Brien contacts Bashir after his interrogation he asks Bashir: "Has Sloan questioned you yet?"

Bashir: "Yeah we just finished."

A few lines later

O'Brien: "He just grilled me for over two hours."

........Wait what?
