after read more...
now to answer my own questions now, please correct me if I'm wrong or
missing anything...

:help filetype tells:
---------------------------------------
turn file type detection on [:filetype on] =>
locate and load filetype.vim =>
it contains: autocommands for the BufNewFile and BufRead events
fail? =>
locate and load scripts.vim , and detect from the contents

turn plugin option on [:filetype plugin on] =>

locate and load ftplugin.vim
load ftplugin/ and all its files


:help runtimepath
---------------------------------------
tells in what sequence the above files/folders should be searched and
loaded. ALL (not the first found) found files/folders will be loaded.

another email from the vim_use group (Gary)
--------------------------------------
so anything you set in ~/.vim/ftplugin/python/python.vim may be
overwritten in /usr/local/share/vim/vim73/ftplugin/python.vim. You
can add code to your plugin to prevent the contents of Vim's plugin
from being executed, but that isn't what you want to do here.
Instead, you should put your option setting in
~/.vim/after/ftpluin/python.vim or
~/.vim/after/ftplugin/python/python.vim so that yours is set after Vim's.
