I think that the technical answer is: it so because the actual refdes
and net renaming is done by gsch2pcb or pcb (via the import
schematic), not by gschem.

And the reason it is so might be that when you do down-schematic to
the source schematic and you want to change it; when you save the
changes to the original file, it should not contain the
refdefs of the final product, since then you will get into trouble
when you include that source sch into some other project.

Thought I would like to see some indication that I'm in a subsheet
(yes, I might forget that after a whole day), I think the analogy
"subsheet refdefs/nets" vs. "a functions local variables" is useful.
