Overwriting the existing property with alias

[QtYury]

I got this code from http://qt-project.org/doc/qt-5/qtqml-syntax-objectattributes.html#considerations-for-property-aliases (I made small modifications)
@
import QtQuick 2.2

Rectangle {
width: 360
height: 360

Rectangle {
    id: coloredrectangle
    width: 100
    height: 100
    border { color: black; width: 1 }
    property alias color: bluerectangle.color
    color: "red"

    Rectangle {
        id: bluerectangle
        color: "blue"
    }
}

}

The resulting rectangle is white. Why? I was expecting it to be blue.

alias 'colour' actually refers to the blue rectangle colour. colorrectangle should be 'red'. It will not change to blue as it is just a alias. It should have been set to red internally. Since it is not setting to 'red', I feel it is bug.
