That's true in general, but for the example he gave ('start from here')
it should be OK, because 'from' is a keyword, so Python will throw a
syntax error before any code is executed:

>>> def test():
        start from here
...   File "<stdin>", line 2
    start from here
             ^
SyntaxError: invalid syntax
>>>
