  Ha, good point. I forgot about Sneakers. This is a bit different though. The idea is that both parties should see the same authentication string and then verify verbally what that is. Say they see "123" so Alice say "I have 123 as my SAS code, what do you have?". And "Bob says, yap I have 123 as well". If Eve is in the middle then she would show "123" to Alice but maybe "456" to Bob. She would have to fake Alice's voice and tell Bob the code is "456" and it's ok. Then to Alice in Bob's voice that the code is "123" and it's ok. All in such a way that Alice and Bob don't suspect anything (has to be realtime too). So this kind of software might make that easier. The way to bypass that is to use dictionary words instead of numbers but then also refer to them further in the conversation. (see silly example in a sister comment about it).
