The camera makes a guess, and it's very very rarely "correct." There's a thread here: http://photography-on-the.net/forum/showthread.php?t=105117 which may give you some insight into WB and how to get it correct.

Their will be times when the camera just won't even come close to being correct, like under tungsten lighting. If possible on your cameras try setting the White Balance to the Tungsten setting and see what happens. Or shoot a grey card and set a Custom WB. Or shoot RAW and use the RAW editor to set the WB to something that looks good. (Much of this is explained in the thread above.)

If you aren't using RAW, then I suggest you forget about the cams AutoWB. Look at what happened to the colors here:
Gray card: Why your meter may be lying to you! I started out to check one thing & learned about another.

Gray Card…White Paper. What’s best?

with white balance does it matter if you detect white in the scene.. does it matter if its in the foreground or background

do white balances change from picture top picture. say if one shot is very shaded then its got a higher level. so would it be true to say that every picture is different?

White balance is a measure of the color temperature of the light illuminating the subject.

If the light changes, the color temperature of the light MIGHT change, and in your example of one shot being shaded and another not, it would change. so you could easily be correct that every picture is different. The exception of course is if the light remains the same from picture to picture.
