Does the output voltage depend on the resistor?
If there is an open loop between node1 and node2, no current flows through R2 resistor so there will not be a voltage drop across it and the voltage between the nodes is equal to the voltage across L1. For instance, most of the voltmeters do not conduct current and form an open loop due to their high resistance. But if there is a current flowing between the node 1 and 2 then there will be a voltage drop on R2 resistor and the output voltage is not equal to the voltage across L1.
