You have misunderstood how the parent relationship details in the Data Dictionary are used. They are used to construct the ON clause in JOINs when an sql SELECT statement is constructed, as documented in Using Parent Relations to construct sql JOINs.

They are not used to modify the WHERE string which is passed from one object to another as the receiving object has no idea which relationship is being used. This is documented in Different names for the same field.

This is also described in FAQ129.
