Indeed.  But this does not make them wrong.  I do not doubt that they
can be translated into spacetime language, but see no advantage from
this.  In fact, they become weaker in this way.

With statements about causality the weakening becomes even more
obvious.  As far as a translation of causal statements into spacetime
language is possible at all, it has to be formulated in a language,
which does not lead into contradictions if applied to solutions with
causal loops, like the Goedel universe.

So I doubt that "clarification" is the appropriate word here.
