I had a regular EOTech and a backup flip up rear sight on my M4. Still had the regular front sight post. Worked really well.
Only reason I can think of having elevated sights is for NVGs. In that picture the optic looks like it is mounted as far forward in the receiver as possible. With the older (aka larger) EOTechs, it was tough getting a good cheek weld and having enough room for the NVG tube to fit.
