Note the sentence: "And although the video does not make it clear, the
first and second stage of the rocket are powered by the same four rocket
engines that are mounted below the payload fairings"
The video on the contrary shows stage two having 4 *separate* smaller
engines requiring a second mixed fuel tank. The first stage fuel tank *incl.
its 4 engines* are separated on the clip. Having exhaust near the first
stage sensitive C2H2 /N2O tanks in the configuration does not make sense to
me.
Now if for staging purposes , only the first stage mixed fuel tank mass was
gotten rid of, a separate second stage fuel tank would be required to
continue powering those same first stage lateral engines.
