Well, presumably you understand that in Python, indentation defines blocks
for things like if and for. If there's no else clause for an if, Python
will resume execution at the next line that is indented at the same level
as the beginning of the if statement. In this case, there isn't one,
because the surrounding block - ie the first if statement - is complete.
So, it's going to skip over the else clause belonging to the outer if, and
carry on at the first line at that level - which now is the one starting
with `variables`.
The upshot of all this is that if the form is not valid, it will skip right
down to the bottom and execute those last two lines, which render the
template with the invalid form, and return it.
