Hi Angier,

Relays are mechanical devices, not solid state, and as such really don't
care which terminal has current coming in, and which going out.  A relay is
nothing more than a solenoid actuated switch, and the schematic is a
representation of the wiring, not necessarily a map for the routing of the
wires.  When you wire up your system you will be running wires in whatever
way will give you the shortest run or the most accessibility, and unless
you're dealing with solid state (polarized) devices, in general all you're
going to be doing is connecting the dots.  I hope this helps.
