that will work, because you have an explicit page break.

referring to the value of a (different) counter changed at shipout
time is just as unreliable as referring to the value of the page
number, in general.

i don't understand well enough what you're actually trying to achieve
here, but this has all the hallmarks of one of those things that screw
themselves up.


     Page object: \pdfpageref\value{absolutepage}\\
     <lots and lots of text so that there's enough that there will be
     a page break in it>
     Page object: \pdfpageref\value{absolutepage}

     new paragraph of stuff...

is the reference right?
