The panel circuit connections are in effect, feed & return.
For a Pos loop, a Pos fed to the 'return' side of the pair will make the pair 'closed circuit', likewise with the Neg side.
Over the years I've done this as a temp repair, many times, until the work can be completed correctly, usually the fault of decorators, builders etc.
