I think so. The loosey-goosey language of "if" is usually (would need to actually check this) interpreted as an implication relationship

"B if A" or "If A, then B" interpreted as

A -> B

The fallacy would then be to do the following

A -> B

B

------------

A

On the other hand, iff is interpreted as A <=> B

i.e. A -> B and B -> A

So you can get A or B if you have B or A respectively.
