Meeting Time Limit Confusion

The Zoom FAQ indicates that as a paid meeting subscriber I can host a meeting up to 30 hours, way past my needs. I need to host a meeting that lasts 6-7 hours and to which intermittent attendees may attend. The 2nd info posted in FAQs contradicts the first, indicating that if the meeting has no participation for a period of time, it will be ended. This is what the FAQ says. Can someone explain the difference between these two scenarios?

Thank you! Richard

Meeting ends after 30 hours (active or idle)

• 1 host, no participant
• 1 host, any number of participants
• 0 host, any number of participants (join before host)

Meeting ends after 40 minutes (active or idle)

• 1 host and 1 or more participants joined. Only one person remains in the meeting. The meeting will end 40 minutes later if no one else joins. 

Note: The meeting durations for paid users only apply to users assigned a paid license or using Webinar licenses (for webinars, panelists are treated the same as participants, however, attendees do not affect time duration). Users with basic (free) licenses on Pro, Business, or Education accounts are limited to the free license meeting durations. However, if a Basic user schedules a meeting and starts that meeting from a paid Zoom Room on the same account, the meeting will not end after 40 minutes, despite the number of participants. If the Zoom Room is a free trial, the meeting will still time out.
