order of vertices of polyshape is not same afterpolybuffer command

x=rand(10,1);

y=rand(10,1);

k=convhull(x,y);

A=[x(k),y(k)];

polyin = polyshape(A);

plot(polyin)

polyout1 = polybuffer(polyin,0.0005,'JointType','miter','MiterLimit',2);

hold on

plot(polyout1)

w=[polyin.Vertices ,polyout1.Vertices ];

in w i want to match the values of polyin and polyout1 . the same edge vertices of polyout1 should be infront of polyin. y the order changed ?
