As you can see in the screenshot of the F.I.S.H. above, the game directly refers to it as "the Tic-Tac-Toe code", not the Pigpen cipher. In addition, the Pigpen cipher uses only one tic-tac-toe shaped decryption chart and two X-shaped decryption charts, whereas TTT uses three tic-tac-toe charts and thus contains an extra cipher letter, which means that the two ciphers are not exactly the same. The Trivia portion of this page directly links to the Pigpen cipher's Wikipedia article.
