Thank you for the insight.
Does this mean the issue is only with dynamic forms? Using iText, I could get
correct page count off other reader 8.x PDF docs?

Yes, but Acrobat/Reader 8.x and Acrobat/Reader 7.x treat dynamic
forms VERY differently.
Acro/Reader 7 would create a "classic PDF mirror" of the dynamic
form, so that non-XFA-aware tools could do some basic processing on
the PDF (as you are trying to do) - but too many problems were caused
when the form was reloaded into Acrobat/Reader and the changes made
outside were blown away.
To avoid this, Acrobat/Reader 8.x no longer creates the mirror -
instead it just keeps a "shell" around...
