Simulink: Assign not using Y0 to initialize output in For loop

I am attempting to swap elements in a vector in Simulink using the Assign block inside a For loop. For the first iteration of the loop, the code works properly and swaps the elements. On the next iterations, it appears that the Assign block is not using the Y0 input to initialize the output Y. Instead, it appears to only replace the U value and does not update the remainder of the vector with the new Y0 data.
How do I ensure that the output Y is reinitialized by the input vector Y0 before the element is replaced in every iteration of the for loop?

It would probaby be a lot easier to write and understand this if you use a MATLAB Function Block

Any solutions yet? I´m facing the same issue right now.

I got it working by seperating out the assignment. So I have two subsystems, the first to assign row "i" and the second to assign row "j". It doubles the number of iterations, but it is the only way I could get it to work.
