Sounds like a typical tight tolerance part with 100% inspection, perhaps for statistical process control, likely by the manufacturer, not BMW.

Just a good guess and that seemed to be reinforced by you specifically noting the reinstall of the 088/089s.
You can probably get a good idea on the 702/703s after reinstall with a single test.
