Its a little thought experiment. Below you see a transmission line consisting of 2 parallel wires. With an LCR meter, I am measuring the inductance of the cable. On the left side, the LCR meter measures one cable. On the right side, the transmission line is shorted out at its far end. The LCR meter measures the inductance of two cables.\$\begingroup\$ The data sheets for most transmission cables (coax, twisted pair etc.) state most things. Normally you can pretty much ignore G up to hundreds of MHz. Above 100 MHz G starts to be more significant due to dielectric losses. You can even derive L and C from internal cable dimensions to a reasonable degree. \$\endgroup\$ –
