Why Does Full Wave Rectification Create Opposite Polarity in V1 and V2 Plates?

"Throughout the period of time during which the plate of V2 is negative, the plate of V1 is positive". Can anyone please explain why this is the case?

The two plates (anodes) are driven by the opposite ends of a centre-tapped transformer secondary winding. The AC potentials at the ends of such a winding with respect to the centre tap are in anti-phase to each other. That is to say, when one goes positive, the other goes negative.

The 5U4 filament is attached to the transformer CT

Sorry; I meant to say that the dc voltage is developed BETWEEN the 5U4 filament and the transformer center tap (CT), as shown in http://www.tpub.com/neets/book6/22b.htm.
