You partly missed Dan's point.  By 'non-($n) case', I think he was 
referring to "plot 'bla1' u 1:2:3".  And yes, that's supposed to behave
differently from "plot 'bla1'".  The documentation even says so, right 
there in 'help using'.

No, the example matches the 2D case of your example quite nicely.  It 
doesn't match the 3D case as well.  I suspect that's because splot never
used to have a 2-column default case back in the days when 'missing' and 
'using' still worked as documented (before pm3d, among other things), so 
there's nothing for using-less splot to fall back to, seeing a data 
record with 2 usable entries.
