Take cheek weld for example. With irons, a consistent chekweld is essential while with a RDS head position has broad parameters. Putting your head in the same psoition makes putting the dot on target very natural and easy. While varying head position complicates finding the dot on the target. When fractions of a second count, simplicity reigns supreme.
What if you, say, use a flip up BUIS with an absolute co-witness to your RDS, and train with the sites up, only viewing the dot through the sites?
