Thanks for the clarification. The Record Reference Manual (Chapter 1)
reads:
"For input links such as INP or DOL (desired output location), if they
specify PP, they will cause the record whose address they contain to
process when the records containing them are processed ... This means
that the value will be retrieved from the specified record only after
the record has processed its data."
Which I had understood to mean that the input link would in fact fetch a
fresh value.

Your understanding of what was written was correct, unfortunately the
wording is actually wrong. I have modified the Wiki version of this
paragraph to mention the async behavior, although it really needs
someone knowledgable to go through this chapter to find and fix up this
kind of problem with the wording. Any volunteers out there?
