Dear @railmanbros. I happened to find out in the internet that the 1 pantographs are used also in Japan where the Alternative current is supplied. They divide the trolley wire in to several sections in order to maintain the voltage but one transformer can not be connected to their neighbor transformers due to the phase and voltage difference, thus, they want the single panto-graph not to short circuit the two transformers. Direct current with relatively low voltage can handle this difference.

To collect enough electric power, 2 pantographs are needed for DC1,500V while 1 pantograph is enough for AC20,000V area in Japan.

p.s.
In Japan, JRs have following areas.
DC1,500V 1067mm narrow gauge
AC20kV 50Hz 1067mm narrow gauge
AC20kV 60Hz 1067mm narrow gauge
AC25kV 50Hz 1435mm standard gauge for Shinkansen
AC25kV 60Hz 1435mm standard gauge for Shinkansen
