ssh_config "Tag" - really only one?

Hi,

I have recently started using the "Tag" keyword in ssh_config, for 
example to select the BindAddress without having to reiterate it in many 
places or to force a dual-homed host to AddressFamily inet6.

This is not always behaving as I intend it to do.

Is it possible that ssh will only allow ONE SINGLE tag to be applied to 
a connection? If so, that comes as a surprise since when the rest of the 
world talks about tags, they mean that they "allow objects to have an 
arbitrary number of freely named, reusable tags attached to them, 
primarily for categorization and filtering".

Thanks for helping me debugging my configuration.

Greetings
Marc
