That is gibberish. It doesn't mean anything.
What you want is:
start /B XWin-works :0 -query host1
start /B XWin-works :1 -query host2
I've tested this and gotten two distinct sessions to one machine (say,
host1) at the same time. I don't currently have two XDM hosts, but I'm sure
it will work fine with two hosts.
Let me know how this works.
