Others have correctly answered your questions, but I figure that
since this is a new feature I should provide my own "official"
answers.

They're applied to the full name of the page.

Yes.

This is the purpose of the nested { } -- you would use

    {{$BaseName}$Group}

For a page like "Stories-Highlander.DeadlySecrets", 
{$BaseName} would become "Highlander.DeadlySecrets".  After
the substitution the above would then become

    {Highlander.DeadlySecrets$Group}

which is then evaluated to return the base group ("Highlander").
