Yes, that was deliberate. If the "zo'e noi" phrase is to truly be
a constant, it must not mention any externally bound variables. I was
missing a {zo'u}, though.

You're right, they probably are equivalent ('probably' because it
depends on the semantics of zo'e, which are murky). I should have given
a more complicated example. Make it:

{ro da zo'u da brode lo broda be da bei de be'o de}

The options are now:
(i) {ro da su'o de zo'u da brode zo'e noi ke'a broda da de ku'o de}
(ii) {ro da su'o di zo'u da brode zo'e noi su'o de zo'u ke'a broda da de
    ku'o di}
(iii) {ro da su'o daxivo zo'u da brode zo'e noi su'o de su'o di zo'u
    ke'a broda de di ku'o daxivo}.

(Again, giving variables different names where possible, for clarity,
and explicitly putting in the {ke'a}s this time.)
