backspacing is measured from the inside edge of the wheel to the mounting surface.
as the backspacing number gets smaller the wheel sticks out further which means the offset goes negative.
so if the offset is positive the backspacing is larger causing the wheel to stick in more.
wider stance for a low backspacing and negative offset.
here is what throws all that off though.
you could have a 12" wide wheel, a 5.5" backspacing and a -25.4mm offset and the wheel will be pretty much centered.
hope that helps
