What is a pause, suspend, and resume in Subscriptions?

Here is an explanation for all three terms:

• Pause - You can stop auto-generating an invoice for a particular subscription temporarily. The status of the subscription will change from 'Active' to 'Stopped'. 
• Suspend - You can stop generating an invoice permanently. The status of the subscription will change from 'Active' to 'Stopped'. 
• Resume - Resume the paused or suspended subscription; the frequency will be set automatically. When you resume a paused subscription, the status of the subscription will change from ‘Stopped’ to ‘Active’. When you resume a suspended subscription, the status of the subscription will change from ‘Suspended’ to ‘Activation Pending’.
