The difference is that "lexicographically" has a recognized precise
mathematical meaning. Your alternatives don't convey that meaning to me
unless you describe what you do with the results of the sequential
...compared by comparing corresponding items, sequentially until an
unequal pair is found, and using the comparison value from that pair.
If all compared pairs are equal, the result is the same as if the
lengths of the lists were compared.
But that seems a bit cumbersome to me...
