wfmash: too many alignments with v0.12.6

Hi developers 😃

running

wfmash \
    scerevisiae8.fasta.gz \
    scerevisiae8.fasta.gz \
     \
    --threads 4 \
     \
    -n 7 -s 5000 -p 90.0  -X  -l 25000 -k 19 -H 0.001   -2 30 > scerevisiae8.fasta.gz.paf    

It seems I am getting too many alignments?

I would have expected to only get the diagonal output in an all-vs-all setting, right? Or am I missing something?

Best, Simon
