IF AND ONLY IF
Can someone explain to me the implication of this statement? I know it sets up a two way street between the two terms but why is that the case???

I've been noticing a lot of biconditionals in the rules of the logic games in the 50s PTs so far, and I believe the wording goes something like this:
Either A or B, and not both
indicates A<-->/B
same as A->/B and /A->B
If A then B otherwise not B.
indicates A<-->B and /A<-->/B
same as B<-->A and /B<-->/A
I hope I did that right.
Is there any other wording that would indicate biconditional?
Thank you JY for the LG videos they are SO helpful and much better diagrams than other books.
