It Makes Sense Though...

If you think about the challenge of deceleration from a purely "basic physics" perspective (i.e. conservation of momentum), then the heavier the capsule, the more energy it will take to decelerate it, using

F=ma

So by ejecting the heatshield before the decelerative burn, you are basically going to get a greater velocity change [through the deceleration] for the same energy [fuel] cost.
