In a word yes.
There are many reasons why this is so. The vertical rate of descent which is what has the potential to give your spine a jolt (sorry vertical deceleration - must stick to technical terms) is under the control of your left hand. Even if you goof (sorry - make an error of judgement) and leave a highish rate of descent then everything under your bum (sorry under the base of you spinal column) which includes various amounts of crushable structural material and finishes up with a cushion (sorry - jolt alleviator) designed to help out with leaving you undamaged when you eject, then the likelihood is that you will feel no pain.
