>>The thread was about baking pita with no pocket...
>In grocery-store nomenclature, "pita" has a pocket, "flatbread" doesn't

I agree...
A pita bread is called a pita bread if it has a pocket.... A pita bread
is defined in the Encylopedia Britannica Standard Edition 2005 as
" Pita bread is a very thin disk of yeast-leavened dough that has
been prepared so as to cause separation of the top and bottom surfaces
of the baked product except at the circumference."
Therefore a bread that does not have a pocket does not qualify for that
name;
Pita bread is classified by the Jalal Qarooni a world renown authority
of of flat breads and the author of the comprehensive book titled '
Bread Technology' as double layered bread along with the Lebanese
mafrood and shamii . Saudi Arabian khubz and shamsi and Egyptian
baladi in contrast to the single layered flat bread like the Afghan
tamees , ,Iranian lavash,...Indian chappatti
