What does ‘No Inter Partes Questions Discussed Ex Parte’ mean in patent examination?

In patent examination, ‘No Inter Partes Questions Discussed Ex Parte’ means that an examiner is not allowed to discuss issues involving multiple parties (inter partes) with only one party present (ex parte). The Manual of Patent Examining Procedure (MPEP) Section 713.06 states:
