I guess it's behaving as it should..
Initially, 
left component = null, RIght component = "Right_First"
After RTL orientation is invoked
left component = "Right_First", RIght component = null
AFter setRightComponent
left component = "Right_First", RIght component = "Right second"

If the application is programming that way, I guess it knows what it is doing, what's the confusion in that case?
