Apparently you cannot clone an auto using any conventional methods because the clone takes the same age as the parent plant and will continue its life cycle and flower and die at the same time as the parent. So there is no point because it won't produce a larger yield. In fact, I could see it decreasing yield because it will have to spend some time recovering so that piece won't get as big or produce the same amount of bud as it would have on the parent plant. As for cloning clones, you can do that just fine. A clone is 100% the same as the parent unless a mutation occurs, and it is no more likely for that to happen to a clone than for it to spontaeneously happen to a plant from seed or for the mother plant to randomly mutate. Plus, of all the possible mutations, even if it does happen to happen, you would most likely not be able to tell without dna analysis. In other words, you're fine doing that with regs but autos there is no point.
