What is Index Property in descriptive programming?

Index property is used to identify a test object uniquely.
Index value is specific to each object.
Now the basic premise of descriptive programming is to identify objects on the basis of its properties.
The Index property and its value directly negates the basic principle of descriptive programming and hence it is a bad practice.
