I don't think you can "explain" relative positioning that way, because that's true for any positioning value, but fixed. The offset (200px in that example [1]) is not in relation to the document. If it was the case, a left-margin or a left padding on the reddish box should have no effect on the blue box. If such styling has an effect on the box, it is because that blue box is offset from *its* normal position in the flow. *its* position, not the position of siblings, or document, etc. That's the reference point for the 200px, nothing else.
