I do currently spin high cadence.

If the recovering leg is pulling up, the opposite pushing leg is either giving positive (pushing), neutral (same force as pulling leg) or negative force (braking effect). If its negative then we are wasting energy. If its neutral then both legs legs are sharing the effort. If its positive then the recovering leg is going to act as a brake. So to be efficient there is only one answer = neutral. I dont see how that gives more power.
With flats I TAKE the weight of the recovering leg but not so much to lift it off the pedal in a CYCLING motion, the work is done on the down stroke.
So yes do you iether share the finite energy between the front and back muscles or just use the front muscles. Im not sure either way whats best but admit its difficult to argue against sharing over two muscles.

Ive never stated flats are better, my original statement was " But don't get exited regarding performance. IMHO for the recreational and sport rider there are no great gains to be had"

I ride rollers in the garage with flats, I have a smooth technique, im not nudging the bike forward every stroke.
