With that definition of equivalence they indeed are not equivalent.
Under some substitutions you can even get ungrammatical stuff. Nobody
has claimed that you can do that.

(1') is ungrammatical. The right substitution would be {ci da poi ke'a gerku}.
You can't express the inner quantifier directly in {da}-notation.

{ko'a pencu ci da poi gerku} does assert that ko'a touches each of three
dogs, that's in perfect agreement with logic. If you want to find a
difference it will have to be in the {lo}-version. I think everyone
agrees on the meaning of the {da}-version.
