This is correct, with some observations:
1. server 1 and server2 cannot be active at the same time (you will
   either have to switch between them as between virtual consoles with
   Ctrl+Alt+Fnn, or one will run inside a window connected to the
   other, but unless you move mouse in that window, the second server
   will be idle, and this is a virtual server anyway).
2. Display11 Display12 and 21 22 are actually called screens by X
   the combination Server1+Screen11+screen12 is one X display, and the
   other is another display.
3. on a physical computer 2 guys cannot use X at the same time, so only
   one X session (read DISPLAY) is active at a time, and they cannot
   share any resources anyway when they switch from one to another by
   using X event communication mechanisms.
