Do you mean two screen 'processes', when you say two screen 'sessions'?
I guess it is processes. When screen -list lists, say, 10 entries, according to ps I also have 10 instances of screen.
Also, what exactly do you mean by 'drawback'?
Resources usage. If start with 5 screen instances, detach, and on reattaching as explained I end up with 10 screen instances, that, in my opinion, is not an efficient use of my resources.
