Summary: a DC restorer is like a power supply where the bottom of the filter cap is connected to video (which is the source of the charging pulse) instead of ground.
A DC restorer is the same as a power supply circuit, with the ground moved from the usual place. The pulse still appears across the diode, the cap still holds a DC voltage across it. It's just the reference point for voltage readings to chassis that has moved.
Pulsed current comes in, but continuous current can go out.
