Yeah that sentence is unclear. It's actually referring to the initial subscription request that triggered the hub sending this verification request, in contrast to when the initial request was to unsubscribe. I've updated it to the below:
Hubs MUST supply this parameter when hub.mode is set to "subscribe". This parameter MAY be present when hub.mode is "unsubscribe" and MUST be ignored by subscribers in that case
Subscription verification requests, no? Hubs do not send subscription requests...
