There's no reason to append this extra slash, (foo/)#hello works fine
to match bar/hello (but not /hello).
% touch a/b/c/hello
% print -l ((^Volumes)/)#hello
a/b/c/hello

Afaict, ((^Volumes)/)#^Volumes should work fine there.
% touch **/*(/e*'REPLY+=/bar'*)
% print -l ((^Volumes)/)#^Volumes
a
a/b
a/b/bar
a/b/c
a/b/c/bar
a/b/c/hello
a/bar
