These are complete different matters. XeTeX *needs* two runs
to get the page labels right. In pdfTeX or LuaTeX the
page label settings are done at the end of the compile run.
XeTeX (or TeX) do not provide the possibility to emit
\specials *after* the last DVI page. But *all* pages are
needed to know what \thepage for all pages look like.

Why there is a warning that a destination name is undefined,
I do not know, because it works for me without this warning
(biblatex 2011/11/13 v1.7).
