Understanding the "Center" for RadialGradientBrushes

Question

I am trying to understand what a property does Centerin RadialGradientBrush. MSDN says: "Gets or sets the center of the outermost circumference of a radial gradient." But when I set its value, I get results that do not make sense to me.

For example:

    <Rectangle Margin="10" Width="200" Height="200">
        <Rectangle.Fill>
            <RadialGradientBrush  Center="0.5,0.5">
                <GradientStop Color="Green" Offset="0" />
                <GradientStop Color="Yellow" Offset=".5" />
                <GradientStop Color="DarkRed" Offset=".5" />                        
                <GradientStop Color="Black" Offset="1.2" />
            </RadialGradientBrush>
        </Rectangle.Fill>
    </Rectangle>

Using the default value for Center, it gives me something similar to this:

This is what I expected. But if I change it to = "0.5.1", I get the following:
