Not at all (love that phrase, btw!) - it is a little confusing.
And your trick of recording the meter is a great idea - I must try that. Don't know why I didn't think of it myself - I work with high-speed imaging!!
Here's an image that might help you understand this a bit better...

this web site...
You are trying to determine the voltage drop across the positive cable (the red one) and normally you would place the meter as shown. On a X5 this is hard to do due to the cable length. Using the cigarette lighter socket gives a "near enough" value, as the cable feeding the cigarette lighter socket runs back to the battery (+) and as long as it isn't carrying any current, there will be negligible voltage drop on it.
