Composer Group Question

Lets say I have an object that is created multiple times to the same local variable.  Do I need to insert it into my group multiple times as well?   Or would I just load it once?  

Example:

Is this correct?

local menuBack = display.newRect( display.contentCenterX, display.contentCenterY, 280, 360 )

sceneGroup:insert( menuBack ) 

local menuBack = display.newRect( display.contentCenterX, display.contentCenterY, 100, 100)

sceneGroup:insert( menuBack )

Or is this correct?

local menuBack = display.newRect( display.contentCenterX, display.contentCenterY, 280, 360 )

sceneGroup:insert( menuBack ) 

local menuBack = display.newRect( display.contentCenterX, display.contentCenterY, 100, 100)

@warrenkuhl,

The first case will insert both objects in sceneGroup - So this is ‘correct’

The second case will only store the first object in sceneGroup.

However, why not just do this:

display.newRect( sceneGroup, display.contentCenterX, display.contentCenterY, 280, 360 ) display.newRect( sceneGroup, display.contentCenterX, display.contentCenterY, 100, 100)

I know the basic examples show calls to some_display_group:insert( some_object), but it is so much better to just pass the group as the first argument.
