Good question. So the shorter ROM versions are supposed to be done with very heavy weight and very explosively. If your structure and form cannot support the load then you will perform the reps improperly and they won't transfer to anything except making a horrible instagram video. When you start with the lighter versions with longer ROM, you train the muscles and the form to keep structural integrity, over time slowly exposing the body to heavier weights so that when you do get to rack pulls and power cleans you can exert maximal force on them without buckling under pressure. The other reason is the rate of transference. You want to go into a season or competition being strong and explosive, but if your training cycle ends with you doing 82x2 deficit snatch grip deadlifts, then you'll go into competition slow and sore. Does this make sense?
