S80 Wheel spots S80 2001

I just posted three pictures of some weird spots in the Technical Gallery that have begun appearing on my aluminum wheels just this past week. I have owned the car since new and never seen this phenomonon before now. The most recent service work where somebody other than myself touched the wheels was a brake job 6 weeks ago and the marks have not been visible until just the past few days. I wonder if anybody has some logical explanation for these marks...other than vandalism (which I seriously doubt). Any feedback appreciated.

    I cannot find the valve stem in your wheel pics.

    Do these spots line up with the valve stem location?

    My theory, these marks were made by the tool that makes the valve stem hole in the wheel, the machine malfunctioned, but stopped drilling immediately after it realized that the drill was not deep enough to be in the correct location.
