This is only possible because of the phenomenal readout speed of the sensor (and stacks of processing power, of course), and even then it’s limited to 60p. Who knows what it does to the appearance of motion blur when the subject moves between the two exposures. Probably bad things to the critical observer.
Arri does something quite different (and less ambitious but with no chance of compositing errors). Those cameras read out the same exposure twice at different gain, for the minimal benefit of operating the ADCs in their highest performance window for both shadows and highlights. In the high-gain readout the highlights would be blown, but that doesn’t matter because they’re preserved in the second low-gain readout.
