If you control the other application (Application X), then when you launch it pass in another value in the extra data part, and don't specify the screen orientation, but, if the intent has this other value set correctly then it is forced to landscape mode.
So, basically, the default is to not force the orientation, but give a way for this other application to be able to request landscape mode. To make it more flexible, you could just allow programs to request landscape or portrait mode, if you want it more flexible.
