It should become clear if you look at the schematic in the AVO EMER manual in the link below:

The 250 volts g2 is from a separate tap to the 250 volts anode supply, that's because although the voltage for the anode is given in "DC" terms the actual voltage is AC and it's nominally 1.4 times greater than the indicated "DC" voltage on the anode voltage selector switch, hence your resistance reading on the 250 volts settings between those two selected voltages of the same "DC" magnitude.
