Yes, this is correct.

Okay, I double checked running an simple X with no window manager on it.
In Xinerama mode, there's no way to access to 2nd display neither by
:0.1 nor by :1 or so.
If Xinerama is turned off, it works be specifying :0.1.

This means, xinerama is broken in mga 4.4.

It's partly closed source. I think the parts we're talking about are
open source, so I'll give it a try on the xorg list.
