3551875 - Text reference through SD documents doesn't work as expected

On the configuration activity 'Set Up Text Determination for Billing Item' (ID: 103500), the field 'Refer/Duplicate' is unchecked, therefore according to the documentation of the activity, the system shouldn't duplicate the texts when copying to the subsequent documents, but only refer to the initial text, so then when the first text is updated, it changes on the follow up documents as well. 

However, this is not how the system behaves. The text firstly maintained on the Sales Order item level, if it's updated, doesn't have any effect on the Invoice text on item level.
