Explain the precedence of btrfs properties over mount options

Hi,
The manpage of btrfs property would be a good place to explain the precedence of properties over mount options, e.g. what happens when the mount option compress is set to zlib and the property for same subvolume is set to "" (indicating no compression as you know)? What happens when compress-force mount option is specified which doesn't have an equivalent in properties?

Best regards,
Kalle
