With a linear regulator there is one circuit: current in equals current out.
However, internal to a switcher there are two circuits:
1) input side -- the current in equals the current out on the input side (like the primary of a transformer)
2) output side -- the current out the + equals the current into the -. (like the secondary of a transformer)
This would be an isolated DC to DC converter. The return currents are the same for the respective input or output, even if both - pins are grounded.
Politics, Religion and Voltage Regulators. Who would'a thunk it?
A nice summary, thank you. It's pretty much the same for a non-isolated, three terminal regulator, except the return currents are mixed up in one terminal.

Well, it makes a nice change from operating systems, programming languages, editors, indenting styles...:)
