It is because the embedded code block is executed during rendering. See http://msdn.microsoft.com/en-us/library/ms178135.aspx. Therefore if you put the code behind the label, the label is already rendered when the code is executed. If you put the embedded code block before the label it is executed before the rendering of the label.
