One reason for this variable is for uses like FAST Data, which stores
data on a separate Data-Group.Name page.  But displays it dynamically,
formatted nicely on Group.Name.  So to find a page with certain data,
you want to search the Data pages, but return the display page.  This
makes it possible to do that.

I haven't seen the nested thing documented, but thees lines simply
explains how the BaseName variable can be used in a pagelist template.
 If the nesting thing works, it would answer you question below.

See above.

Alternately, though I'm not too good with pattern matching, it seems
you could strip off the prefix, and/or anything after the "." which
wold give you just Highlander.  Of course in the pagelist, you might
end up with a lot of links to default group pages, ie: [[Highlander]].
