Because Geometry is only used for importing, and then the game no longer looks at the content of that link (as far as I remember). Only a clever numerical-alphanumeric code plays a role, which encrypts the geometry file in the resource archive. Sounds work on the same principle, by the way.
In the bin/Geometries folder, there are meshes (in a general sense, this is a static model, as it does not contain animation) in the .niv format without an explicit extension, and the clever numerical-alphanumeric code is a GUID, which is created according to the principle: object creation time * CRC of the mesh * Maya instance ID, i.e., two identical GUIDs cannot exist in principle!
