Hi James
Perhaps "bifilar backemf"  (the inductive kickback spikes from a bifilar coil)
Is of greater power when first you split then combine the inductive kickback spikes produced.
This means bifilar half A is fed the.pulsed DC power (or alternating polarity pulsed DC for AC)
And steering diodes capture the kickback spike into cap (s).
Then the other half (B) of bifilar is not driven by direct power feed but rather is only induced by bifilar half A.
Now either combine kickback spikes from each into common cap or fill up separate caps for each bifilar half.
Could be creating a "coherence" condition as Ole speaks about, from W B Smith writings.
The capacitors filled need to be disconnected from the coil whenever they discharge to load for real power to be seen with no reflection back to primary input.
