This suffers the same problem as the original proposal: it's based on order of
events, recognisable by the use of temporal language ("immediately",
"finally", "when"), and (if interpreted literally) involves a mutable
variable.

I think you have to find a way to do this kind of thing in multiple phases.
For example, first phase creates a composite document, phases 2 and 3 extract
parts of this into different result documents.
