I've never used org-agenda-filter-by-top-headline, but taking a quick
look at it and its helper, org-find-top-headline, the intention seems to
be to find the level-one parent of the current heading.  So, in your
example,

... it'd find "Root" if point were on any of the tasks.  If I'm reading
your report correctly, you're assuming that with point on the "task 2",
it'd take *that* as the top-level heading and filter to all the tasks
under it (task 2.1, etc).  Instead, it finds "Root" and filters to
everything thing under that, which---in your example file---is the same
thing, so you don't see any change.
