This is working as documented. Any paths specified in PYTHONPATH are documented as normally coming after the working directory but before the standard interpreter-supplied paths. sys.path.append() appends to the existing path. See here and here. If you want a particular directory to come first, simply insert it at the head of sys.path:
import sys
sys.path.insert(0,'/path/to/mod_directory')
That said, there are usually better ways to manage imports than either using PYTHONPATH or manipulating sys.path directly. See, for example, the answers to this question.

You could use:
import os
path = 'the path you want'
os.environ['PATH'] += ':'+path

As to me, i need to caffe to my python path. I can add it's path to the file
/home/xy/.bashrc by add
export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH
to my /home/xy/.bashrc file.
But when I use pycharm, the path is still not in.
So I can add path to PYTHONPATH variable, by run -> edit Configuration.

When running a Python script from Powershell under Windows, this should work:
$pathToSourceRoot = "C:/Users/Steve/YourCode"
$env:PYTHONPATH = "$($pathToSourceRoot);$($pathToSourceRoot)/subdirs_if_required"
# Now run the actual script
python your_script.py
