Lets say I have an array X that contains [A,B,C,D,nil];

and I have a second array Y that contains [E,F,G,H,I,J,nil];

If I execute the following:

//Append y to x
[x addObjectsFromArray:y];

//Empty y and copy x
[y removeAllObjects];
y = [x mutableCopy];

What is the value of y? is it?:

[A,B,C,D,E,F,G,H,I,J,nil]

Am I performing the copy correctly?
