IEC 61058-1 Annex F中这一句如何理解?

F.1.2.1 Switches having both resistive and motor load ratings are not suitable for switching acombined load of the full resistive load plus the full motor load. Such switches can be used forswitching a combined resistive load plus a motor load, providing the vector sum of the resistivecurrent and six times the steady-state motor current does not exceed either the resistive currentrating or six times the motor current rating, whichever is greater, and depending upon thepower factor of the combined load. The vector sum of the resistive current and the steady-statecurrent of the motor shall not exceed the resistive current rating.问题:画线的两处是否相互矛盾?
