No it doesn't.  The IIgs file type and auxiliary type are packed
together and stored in the HFS file type field (part of the Finder
Information record).  The HFS creator field is always set to 'pdos'.

You might be thinking of the other way around: copying a Mac file to a
ProDOS volume stores the Mac type/creator in the extended key block, not
the directory entry.

If Mac file types are preserved when copying around from Linux, then
ProDOS ones would be as well.

More likely: Linux just copies the data fork, leaving the resource fork
and Finder Information behind.  A default file type/creator would then
be assigned when the file gets copied back to HFS.

Do you perhaps mean BinSCII encoding?  GSCII is just one program which
supports the BinSCII encoding method (along with several related ones).
