leaves are trimmed back during the cloning process to reduce their surface area and in turn reduce the amount of water that is transpired though them. This slows down their water consumption so they do not dry dehydrate in a few hours time and struggle every day during the rooting period. I do this because it also promotes good air flow around my cuttings and saves me from having probs with powdery mildew and the like during the 10 days they are in a RH of 90%++. Of course i have 40-50 clones at a time packed into my humidomes.
