Do Zoom cloud recordings, record directly to the cloud?

Apologies for asking what might be an obvious question.
Wanting to confirm that Zoom meetings recorded to the cloud are recorded directly in the cloud and not stored locally until the meeting is over to be uploaded or uploaded in real time?

I assumed zoom would grab a copy of each participant stream as needed directly from the cloud server doing the distribution to all participants.

I work in education design for a University, We had an academic say he has to finish lectures in a shared lecture space early because Zoom needs time to upload before he has to log out, if the space is booked back to back. Inferring Zoom was doing the upload, post-meeting occurrence, which doesn't seem right to me.
