IIRC, and as far as the contents of upstream udev rules imply,
    GROUP="foo"
is a shorthand for
    GROUP="foo", MODE="0660"
but I can't find explicit documentation about this at the moment.  IOW if
you specify GROUP, you need MODE only if you want something different from
660.  (And if you don't specify GROUP, you need MODE only if you want
something different from 600 of course.)
