Unfortunately it’s how Blender works : the operator panel only is available for the latest operation
So when you add the mesh , that become the latest operation and so you have the operator panel listing the mesh tweaks/settings/options.
But if you move or rotate, the operator will lose the mesh editing option and will then display the settings for what is now the latest operation : the move or rotate you just did.
Maybe with the Blender 2.7x serie that will see some refactor, it may become possible in the future.
