I'm still working on my timing, so I could be wrong here, but my understanding is that when you turn away, as you start to pivot your upper body, you pull into the right pec area and your shoulders are 90 degrees from the target. At that point, you start your pull and your elbow fires out and stops, your shoulders continue to rotate and your lower arm chops. As it's chopping, your shoulders are coming around so that as your arm straightens and the disc comes out, your body pulls your arm away and keeps you from hyper extending.
I've thrown and straightened my elbow. It hurts, not so much as to injure, but enough that I care not to repeat it.
I think the best way to see it is by watching Brad's slow motion videos. You can see it's so subtle. What you want to look for is how he picks up speed right as the disc comes into his chest.
Basically, what you want to do with the elbow is make sure that it's point out to your target before you pull. That way you harness more power. If you watch newer player's throws, you'll see that their elbow is past the target or way in front of the target when the disc is coming out.
