docs: Evaluate the given greater than match condition for the user attributes.
  
        Args:
          index: Index of the condition to be evaluated.
  
        Returns:
          Boolean:
            - True if the user attribute value is greater than the condition value.
            - False if the user attribute value is less than or equal to the condition value.
          None: if the condition value isn't finite or the user attribute value isn't finite.
