LTspice Save Internal Device Voltages

 

On LTspice Control Panel->Save Default tab there is a checkbox named "Save Internal Device Voltages".
?
I believe it is supposed to save the voltages of "device internal nodes". Take for instance an inductor with a default Rser=1m. For a such device, LTspice employs a proprietary "compound model" based on Norton equivalent in order to reduce the overall circuit's solving matrix size.
?
As explained in Help page, setting Rser=0 forces LTspice to use the "cumbersome" Thevenin equivalent introducing an internal node in the inductor's model. That means the current through the inductor becomes a new unknown of the circuit's solving system (you can check this in SPICE Error log: the matrix size actually increments by 1).
?
That said, I thought the checkbox above added some information about this "device internal node". However, it seems it is not actually the case.
?
Any idea about it ? Thanks.
