Is MDG an advanced dry orgasm?

Recently, I was reading a lot about the science behind the male orgasm and other methods of achieving a high-pleasure state. I noticed that the idea of the MDG sounds very similar to a dry orgasm (or NEO - non-ejaculatory orgasm). As I read about how to achieve one, most tips involved diaphragmatic breathing, pelvic floor relaxation, staying in a high arousal state as long as possible, etc. A dry orgasm is described as waves of pleasure without a refractory period. It sounds quite similar to me, but the MDG seems like a pro-level version in comparison to other things I've read. So I started to wonder: what if we should first figure out how to achieve this type of orgasm, show our bodies that we are capable of it, and learn in practice that pleasure is possible without ejaculation?
