Yes, it is. Let me explain why:

Embperl's [$hidden$] outputs all form fields stored in %fdat, which
have not shown up in the source code before.
At this point no form input fields have shown up, so alle submitted
form fields show up.

Now one of the fields (notice the 'name="foo"') is present in the
source code, so we don't have to output them any more. This is the
reason, why it doesn't show up in the rest of page when [$hidden$] is
called again.

I would just rename the submit button's name to something else than
'foo' and it should work as expected.
