Right. You'd have to start the app on one head or the other. This can make the second head somewhat less useful, but it really isn't a big deal. The major issue I had with Xinerama (other than the obvious OpenGL barfulosity) was - and this is going to sound lame - my desktop wallpaper getting sheared off at the right edge of both heads (Rather than being centered to the overall display or centered to each head... I think this is a wmsetbg bug, though)
