Should this be cced to stable for back port?

I have no strong opinion given this is minor doc clarification update.
Also the related feature is not really exercised until 20.11 really (with new PMD).
Still if you think it is required the change would refer to that commit 3f3f608142cf48
Let me know if I should resubmit.
Thanks
Nic

I applied it as is.
Thanks.
