NFC writerfilter: reorganize and re-use variables

My previous patch for tdf#133000 modified the
code flow a bit. I kept these "formatting" changes
separate so that they wouldn't interfere in understanding
the functional code changes (which is very important for
this extremely fragile numbering code).

In this patch, I relocate two lines to group them
with their logically similar counterpart
and the variables that control it.

I also got really confused by one of my earlier
code comments which seems to be completely wrong or
at best misleading, so I modified it to be what
I think is much more accurate.
