Potentially, yes, but I haven't bothered to define the exact semantics
here (more below).

Answer #1 (short): The behavior of nested double-brackets is in general
undefined.

Answer #2 (longer): Rather than try to come up with an answer for "what 
should happen" in every markup instance, I've followed PmWikiPhilosophy 
#3 and used a simplistic implementation that covers 95% of the cases for 
now (and typically doesn't present too much confusion to the naive author), 
leaving the other 5% of the cases purposefully unresolved until one or two
specific problem scenarios are presented that can guide us towards a
"correct" answer to such cases.  :-)
