Sql server replication for HA and DR

1.)According to brent ozar's HA and DR chart ,for Failover Cluster Instance - SQL Server minimum version supported and SQL Server minimum edition required is given as 'any'. Does that mean it works with sql express? or am I misinterpreting the meaning of 'any'? According to microsoft it doesn't work for sql express. 2.)Same chart also says that sql server Replication can automatically failover. Here is what I found . How does the automatic failover happen in case of replication if it is possible?
