Maximum number of databases that are supported in AlwaysOn?

Hi All,

I believe to configure maximum number of replicas it is required to have 5 nodes (1 Primary & 4 Secondary replicas). But how many databases can be included in one availability group, it think it is 32767. When I am referring to below URL it is mentioned something like "An availability group supports a set of read-write primary databases and one to eight sets of corresponding secondary databases. " What does this 'sets' means, is that maximum limit for only eight databases or maximum groups should be eight? Please advise.
