Blank Pages & Screen Readers

All,

I have been assisting some co-workers and contractors in producing 
accessible, 2-page PDF files from some fairly complicated Word templates, 
while following various guidelines, tutorials, etc. available for this 
workflow (such as Adobe's accessibililty guides for PDFs). Someone 
provided the following statement to me which I have never heard before ... 
and somehow doesn't seem intuitive:

"A third page that is blank was also added because we are told that when a 
screen reader encounters a blank page that's a signal to the screen reader 
that it is at the end of the document."

It seems to me that an end of a document is the end and no further 
"signals" are necessary. I wonder if this is accurate, is it recommended 
as a best practice?

Any information or experiences with this is appreciated. Thanks!
