AFAICS you will need two joins to get the desired output. Otherwise the unpairable records are interleaved in the output. Although getting the unpairable records in a second invocation will always have a fixed order, it's by accident the one you request (add "-v 1 -v 2" in the second invocation).

The strange thing seems to be, that "-j1 2" is handled like "-1 2". "-j 1" should already have an option and "2" would then become the first filename making the last filename in the command line superfluous.
