I guess this is the point you are missing. The definitely IS a potential negative! Your skinks can be seriously injured or killed by each other if kept together. That is why it is recommended to keep them separately. It has NOTHING to do with breeding. It just eliminates the possibility of them killing each other. Some skinks co-habitate fine. Others don't. The problem is, you really have no way of knowing whether they are ok together or not until you come home to find one or more dead or maimed.
I am not saying don't keep them together, only saying that you need to acknowledge the risk before you do. No matter how you set them up, there will still be a risk to the skinks. It is also fairly common for a pair or group of skinks to do fine for months or years before one or more of them ends up being killed by another. Again, not saying it can not be done, I just want to make sure you are aware of the risks.
