Your patch just removes the test for the visibility of the axes, so the 
question is rather is that the right thing to do.. Reading the comment 
of why this test was added I suppose the question is what does matlab 
give for

axes()
set(gca(),'visible','off','color',[1,0,0])

Is a red square visible in the figure or not? and what about

close all
plot(1:10)
set(gca(),'visible','off','color',[1,0,0])

If it is visible in both cases then your change is right. If not then 
some other change is needed
