JMT hygiene questions – poop dirty toilet paper & soap

I've done some research on the leave no trace code in JMT, and realised very high level of nature protection. It made me wonder what's going on on practical level. Anyone could help please? 1) Do you really carry out the dirty toilet paper after use instead of burying with poop? 2) Do you really have to carry then, all scented items including poop toilet paper in your bear can with your food? 3) Do you really don't use any type of soap for your body even away from 100feet from water source? (Is this prohibited? I'm not sure)
