The part you load first will be printed with the primary extruder (the brown part), the green part will be printed with the secondary extruder.
The positioning in RC4 is bugged:

You should slice and check if the result is good, because slicing still gives the correct GCode even if the preview of the 3D model is wrong.
Note that dual head printing is experimental in Cura, and that you have to setup to heat both extruders yourself, as Cura does not do that yet.

Also, how do I then tell Cura which part to print with which extruder?
