Let illustrate an example:

In Freebase we have a type for describing music artists [1] and another 
type for describing music albums [2]. So far so good. However, both 
types include a property 'genre' for addressing the genres of a music 
artist respectively the genre of a music album. Unfortunately, this is 
not a shared property, i.e., there exist a separate genre property for 
music artists [3] and another for music albums [4]. Albeit, a genre 
relation is a genre relation is a genre relation, i.e., one single music 
genre relation with a union domain of music artist and music album 
(etc.) would be enough and reflects how a music genre property is 
defined and understood in reality.

You could apply the same for repeating property definitions in the 
schema.org namespace.
