Why do LINE and PLOT not honor the default properties for a line that have been set using MATLAB 7.8 (R2009a)?

I have changed the defaults for the line on an axis as below. When I plot a line using LINE or PLOT, the figure does not contain the default properties for the lines drawn as I have set them.

h = gca;

set(h, 'DefaultLineLineStyle', '-.')

set(h, 'DefaultLineMarker', 'o')

set(h, 'DefaultLineColor', 'g')

set(h, 'DefaultLineMarkerEdgeColor', 'r')

set(h, 'DefaultLineMarkerFaceColor', 'b')

hold on

plot(0,0)

plot(1,1, '*')

plot(2,2, 'o')

line([0 4], [0 -4])

line([0 4], [-1 -5], 'Color', 'g')

The changed default properties for the axis are honored if LINE is called using the low-level syntax of LINE as below:

h = gca

set(h, 'DefaultLineMarker', 'o')

set(h, 'DefaultLineColor', 'g')

set(h, 'DefaultLineMarkerEdgeColor', 'r')

set(h, 'DefaultLineMarkerFaceColor', 'b')

set(h, 'DefaultLineLineStyle', ':')

line('xdata',[0 4]', 'ydata',[0 -4]')

PLOT is a high-level function and picks up the default properties set for the figure, for example:

set(gcf,'DefaultAxesColorOrder',[1 0 0;0 1 0;0 0 1],...

      'DefaultAxesLineStyleOrder','-|--|:')

t = 0:pi/20:2*pi;

a = ones(length(t),9);

for i = 1:9

a(:,i) = sin(t-i/5)';

end

plot(t,a)
