If you move the camera at all after the metering has been set with the AE-Lock button, the EV value will reflect the difference between what is now in the meter's sight and what was metered on. It's quite sensitive. I often find it is off by .2 to .7 EV in either direction because I don't have the subject centered exactly the same way.
But it is definitely setting the null point.
