It does:
% setopt extendedglob
% cd $(mktemp -d)
% mkdir -p foo A/foo A/B
% cd A/B
% echo (../)#foo(:A:h:t)
A tmp.Ykz8jNBvJo
% echo (../)#foo(Y1:A:h:t)
A
(Also: 'git rev-parse --show-toplevel')

That's the current behaviour:
% mkdir -p A/B/foo A/foo
% echo **/foo(Y1)
A/foo
It may be worthwhile adding a unit test for this to Test/D02glob to
ensure this behaviour doesn't change.
