In mirroring there is no windows cluster but still we can failover, here cluster required for virtual name
or listener

[@chandustechnet4214]

Main thing for automatic failover is quorum/majority number of votes, in mirroring we've witness to maintain the quorum/majority number of votes whereas in alwayson/SQL automatic failover takes care by the windows cluster with the help of quorum configuration and majority number of votes.

How many IP's required for 2 node always on

[@chandustechnet4214]

If your ask is for listener configuration then one virtual IP per subnet. It doesn't matter how many replicas you've.

Long winded waffle that constantly repeats itself and NEVER covers what a leade timeout is

[@chandustechnet4214]

You mean, the video should be more detailed what's the lease timeout?
