You can believe whatever you want but like I said talk to your bank before hand. When I did my Baikal that is what Wells Fargo told me. Also I found this answer on Quora too:
It's not a belief, it's how wire transfers work. If you read the Quora answers carefully you'll see that a reversal could MAYBE happen if there was fraud or error on the sender's side (e.g. insufficient funds) and the funds have not been disbursed. Obviously that would not work if the recipient (seller) is a scammer.
