Orochimaru seems to have genuinely changed by now. If you take his scientific temperament into account I am pretty sure by now he very well understands the ethics involved for experimentation. Considering how both Sasuke and Kabuto fulfill his innate desires to the extremes i am quite sure that he know the outcome of such behavior perfectly well. Not to mention the kind of interest he is showing now to Mitsuki clearly shows that he has turn over some new leaves and perhaps after all Jiraiya's ideas and words finally did reach him judging from the conversation between Tsunade and him.Overall this guarding is more like formality as they cannot let Orochimaru roam free after all he has one but his experiments are still ahead of time. It would be loss if he wasn't allowed to continue. So they are keeping a charade of him being in life imprisonment while he conducts his experiments as always.
