Yes, but ellipsis presumes cooperastive listener and speaker.  I would
undoubtedly phrase the sentece differently to say something like that
(or have context that clearly indicates it).  I guess I could also make
it clear with lekau jei broda , which to me seems more obvious than ledu'u
xukau - which seems very malglico for some reason to me (or malrarna) when
jei is explicitly available.  xu just too strongly asks a question to me, 
even if metalinguistically marked.
