That range gives the mechanical designer room to accommodate component height on the bottom board or airflow clearance without qualifying a different connector for each stack height. The 7.75 mm height above board of the receptacle itself is fixed; the variation comes from the plug side.
The 5-5179009-4 uses a 0.031" (0.80 mm) pitch in a 2-row configuration, typical for high-density mezzanine board stacking.
This receptacle supports mated stacking heights of 9 mm, 10 mm, 11 mm, and 12 mm when mated with the corresponding Free Height plug.
