l can't find the picture of the model, can you repost it?

OK, thinking this through, as the phase of the top 1/2 wave comes across the zero line and crosses over (the high voltage node) into the inverted phase bottom 1/4 wave of the main radiator, the current at it's base is necessarily 180 degrees inverted from the current in the top 1/2 wave doing the radiating, and as you state is undesirable, but if the current which is desirable is at it's 1/4 wave peak node at the base of the antenna where the radials connect then two equal but opposite currents are present at the same point on the base if you also have constructive current there!

And that's where you stated simultaneous inverted current takes place, but that's not possible without cancellation of both currents, leaving none for radiating RF.
