I was also under the impression that most soldiers using an EOTech like that would move their eye up slightly so that the front sight post would not obscure the EOTech reticle. With a parallax free holographic sight like that there is no need to line up the front sight post. As you move your eye around in relation to the sights on your weapon, the EOTech reticle moves with it so that what you see through the holographic reticle is always the point of impact ,regardless of where your eye is, as long as you can still see the reticle.
Here are four pictures of the same gun (not mine, I got the pics from
here).
In the this picture the rear peep sight is raised and as you can see the EOTech will co-witness with the iron sights when your eye is looking through them.
In the next picture the rear sight is lowered and the camera has moved up and left from its previous position in relation to the gun, but due to the way the optics work the reticle appears to move up and left in the sight window as well and is still covering the correct point of impact.
Heres another pic with the camera again in a slightly different position. The EOTech is still showing the correct point of impact.
I personally think the reflex sight picture in PR should look more like the last pic here where the reflex reticle appears above the front sight post to represent a soldier that understands how his optics work and chooses to look through the upper portion of the sight window so that his sight picture is not obscured by the front sight post.
