block=20*ones(200);

Well, in your second piece of code, you're showing A three times. If you show A, B and C you get the same figure as in the first piece:
figure;
subplot(2,3,1);
imshow(uint8(A));
subplot(2,3,2);
imshow(uint8(B));
subplot(2,3,3);
imshow(uint8(C));

Rather your second code should be
if true
% code
A=60*ones(500);
B=120*ones(500);
C=200*ones(500);
A(151:350,151:350)=20*ones(200);
subplot(2,3,1)
imshow(uint8(A))
B(151:350,151:350)=20*ones(200)
subplot(2,3,2)
imshow(uint8(B))
C(151:350,151:350)=20*ones(200)
subplot(2,3,3)
imshow(uint8(C))
end

The two codes will show different results because
In the first code you are subplotting three different images i.e block1,block2,block3
but in the second code your code subplots the same image i.e A three times...this is why you are getting wrong outputs....
