I too get your unexpected result and don't expect it given the logic at
http://git.savannah.gnu.org/cgit/groff.git/tree/src/preproc/refer/label.ypp#n1140

Here's a test case that I think is equivalent to yours for those playing
along at home.

    $ cat hops.ms
    .R1
    database hops.i
    join-authors ", and " ", "
    et-al " et al." 1 0
    bracket-label "" "" ""
    label "@"
    no-label-in-reference
    accumulate
    .R2

    $ cat hops.i

    %T A-Z

    %K ab2019
    %A Alpha
    %A Bravo
    %A Charlie
    %A Delta
    %A Echo
    %T Alphabet
    $
    $ refer hops.ms
    .lf 1 hops.ms
    .lf 10 hops.ms

    .lf 18 hops.ms
