Trying with elisp blocks, I'm not able to reproduce this (pretty recent
Emacs 25, GNU/Linux, latest Org).

How are you calling save-some-buffers?  It should ignore buffers that
aren't visiting files unless its PRED argument is non-nil or a function
that returns non-nil.

Can you step through save-some-buffers and see what's going on there?
Specifically, what's passed in as PRED and what happens here?

    (or (not (functionp pred))
        (with-current-buffer buffer (funcall pred)))

We could `(set-buffer-modified-p nil)', which will force
save-some-buffers to ignore it, but I don't think that should be
necessary.
