Zip-Archive mode has nothing to do with it.  If you edit the original,
unzipped file in Fundamental mode the same thing happens.  This is
because Emacs only checks whether the file has been changed on disk whem
you attempt to change the buffer, since there is the chance that you'll
lose the information on disk.

If you want Emacs to continually check the buffer for you, try M-x autorevert.
