That is because only a layer 3 GRE tunnel requires an ip address.  A layer 2 tunnel does not.

If it is a layer 2 tunnel, there is no ip address; it is just basically bridging traffic.  If there is a layer 3 tunnel, typically there is an ip address because there is a route added to point to the subnet represented by the tunnel.
