Just create a second animatedline and use addpoints:
    numpoints = 100000; 
    x = linspace(0,4*pi,numpoints); 
    y = sin(x); 
    y2 = cos(x);
    figure 
    h = animatedline; 
    h2 = animatedline;
    axis([0,4*pi,-1,1]) 
    for k = 1:numpoints 
      addpoints(h,x(k),y(k)) 
      addpoints(h2,x(k),y2(k)) 
      drawnow update 
    end
