Your problem is, the :redir END part is seen as argument to the :g
command, that is, for each matching line, the :redir END command is
issued and therefore you only get the first match in your register.

To prevent this, you can use :exe if you want to put this in one
single line, e.g.
:redir @c|exe "g/a./"|redir END

See
:h :bar
:h :exe
