Yes, that is correct. *SHELLS DO STUFF*. If you can't comprehend this,
you should get to know your shell. Try this:

python a.py %PATH%

subprocess.Popen(["python", "a.py", "%PATH%"])

Would you expect those to do the same? If you do, prepare for Windows
to surprise you. If you don't, why do you keep expecting other shells
to do nothing?
