I get the same result when I use plot (x,y) instead of replot.
That is having used "axis" without any arguments to get back to autoscaling,
the plot *is* using autoscaling (which is 0, 10, 0, 10 in this case) *but*:

octave:8> axis
ans =
   -1   11   -1   11
octave:9> show xrange
warning: show is obsolete -- use gshow instead
octave:10> 
        set xrange [* : *] noreverse nowriteback  # (currently
[-1.00000:11.0000] )
octave:10> show yrange
warning: show is obsolete -- use gshow instead

        set yrange [* : *] noreverse nowriteback  # (currently
[-1.00000:11.0000] )

The axis arguments given above are not what is being used for the plot. When
I use "axis" it resets the arguments to default *for the plot* but somehow
"ans", as well as "xrange" or "yrange" are are *not* reset.
