Jorge is right. The "possible worlds" gloss of mu'ei and ba'oi is
simply an attempt to model in a formal and explicit way their meaning.
I would do exactly the same for English conditional _could/would_.
If you have a preferred way of modelling English conditional _could/would_,
I expect it could be applied to mu'ei and ba'oi.

Though selmaho are defined more by grammar than by meaning.

ba'oi does that.
