It's not that single ended provides twice as much output per transistor. It's that Single ended gets the full output from each transistor simultaneously while a push-pull pair never gets more than the full output from one transistor at a time. If you know that one MRF421 can support 20 amps of collector current, measure the current drawn by a push-pull pair. The circuit will not support a single amp more with two transistors in push-pull. Using a pair of single ended transistors with combiners and splitters will allow the full 40 amps to be drawn. Doubling the input and output power as compared to a pair in push-pull.
