3:50 there must be a hub if I am not mistaken. But he said it correctly - Two links in one segment.
So the switch4 has actually 2 ports connected to a hub and a hub is connected using 1 link to the switch3

From Cisco's official cert guide book:
"The need for a backup port can be a bit confusing at first because the need for the backup
port role only happens in designs that are a little unlikely today. The reason is that a design
must use hubs, which then allows the possibility that one switch connects more than one
port to the same collision domain

With a backup port, if the current designated port fails, switch can start using the backup
port with rapid convergence"

Hi Paul,

I would like understand the BPDU details such as Topology change notification and configuration change - LSB and MSB in more details.
Thanks for this video.
