I think the logic can be preserved by changing iff to "if", and for any
instances of "if" that do not mean "iff", there should be some wording
like "... may be ... if ... " to indicate that there is not a
bidirectional correspondence.

In general, bidirectionality is assumed by most speakers of English (as
opposed to mathematical logic) for a bare "if".
