This just like the original 'join' depends on the two output from
for-each-ref to be sorted the same way, which is true and fine.  But
I wonder one thing.  When $before has this in it:

        refs/heads/refs/heads/master 664059...126eaa7

and your "read ref a" got this in the input:

        refs/heads/master 664059...126eaa7

would the pattern matching by case work corretly?

Doing something like this might be needed.

        case "$LF$before$LF" in
        *"$LF$ref $a$LF"*)
                continue ;; # matches
        esac
