This is my take on how a cycle reversing valve operates.
Although I refer to a split system configuration as i describe it, it is in fact from a large package unit AC, where the Evap coil is inside the same housing as the compressors and condenser.
I made a mistake towards the end of the vid. The first of the far-side tubes on the Fujitsu condensing unit is actually the suction tube from the Evap coil. Not the tube to the Condensing coil, which is on the far side.
