That is quite true of any new dialog box.-
Joseph Lee once used the term information blackout to describe the idea that any screen reader user cannot ever experience any window, dialog, etc., as a gestalt like one does when seeing it. And it's true, since a screen reader can only focus on an element at a time during the most typical forms of navigation. You can't take it all in at once.
But, and it's a critical but, screen reader users who don't know about this need to, and need to know about the necessity of actually reviewing new windows, dialogs, whatever, in their entirety if they wish to know everything that it contains. Mind you, I'm not insane enough to say this must happen each and every time you happen to "be passing through" on something that's neither of great import nor that you expect to use again. But the PDF dialog, given the context of the original question and the information being sought, is a perfect example where reviewing it, in its entirety, using the method(s) your screen reader gives you, is necessary to know everything it says, at least for a given screen reader.
There is a difference in what NVDA and JAWS announce by default based on the layout of that particular dialog. And in this case, it takes a bit more cajoling to get all the information that NVDA gives by default, which is complete, from JAWS. There are plenty of instances I can recall where the reverse is true, so this is not an insult aimed toward JAWS.
And in any instance, when someone using another screen reader than you routinely do reports that they're getting more information than you are in a specific context, that clearly indicates that your chosen screen reader is, for this context, "missing something" unless you force it to reveal it, if you can force it to reveal it, and you generally can.

It is the function of creative men to perceive the relations between thoughts, or things, or forms of expression that may seem utterly different, and to be able to combine them into some new forms--the power to connect the seemingly unconnected.
