The equivalence you state is a fact about the correspondences between
English sentences and their logical meanings. In principle, Lojban
could operate with different correspondences, so long as they were
compatible with the guiding principles of Lojban.

In practise, the current choice comes down to whether you want
{ro broda cu brode} to mean the same thing as {ro broda ga na broda
gi brode}. It really is up to us to choose; neither choice is
intrinsically right or wrong.
