IMO, selecting the "...and open" option implies that you want to (re-)load the PDF.

Hmm. Not sure if this is strictly speaking a bug. Latex is an external
program and the process does replace the file on disk, so it has changed
compared to the buffer. So at that level, the revert seems normal.

However, Emacs knows this process has occurred and knows it should
re-read from disk as a new PDF has just been created, so perhaps it
should just do the revert without asking? This may have consequences for
users who are working with large PDF documents and high DPI settings who
may not want to re-generate the PDF every time, so it may be necessary
to make the auto reloading an option?

In a graphical emacs -Q instance, open any Org file. Export it as PDF and open
(C-e l o). Then do the same again. Emacs prompts "File foo.pdf changed
on disk. Reread from disk (yes or no)" although no external program (not
counting latex as external here as it was started by Emacs) actually
changed the file.
