One point that distinguishes Scheme's continuations from Classic Lisp's
"catch" is that a continuation can be used "jump into" a function that
has already returned (i.e. that is not currently "active").

What is this property of a continuation called?  In an earlier article
it has been referred to as "upward funargs", but I have also seen
"downward continuations" as well as "upward continuations".  Which is
the correct term?

I have already heard the "upward/downard funargs" thing in other
contexts.  What is the etymology of this term (probably a question for
the Lisp "oldtimers"), and what exactly does it mean?

Regards,
