That's true for the C-level, i.e. main's argv. If you're only concerned about CPython and the program is a script living in a file, then sys.argv[0] is the filename the python interpreter itself used to read the script. Hence it's a valid filename that refers to the script. It may be a relative filename, of course, in which case it won't be correct anymore if the program changes its working directory.
