Think of the sensor mounted on 3 screws that are in the corners of a triangle.

If you adjust all 3 screws by the same amount, you'll move the sensor upwards/downwards, keeping it flat (which you want to do).

If you adjust them by different amounts, you will slant the sensor, and thus could for example cause the left AF sensors to back focus, and the right ones to front focus even if the center one is spot on.

More details:

Thank you very for the useful information and link.

Best regards,
